Walka 7 A portable novelty

After trying DStv Mobile’s Walka 7 for a few weeks, SEAN BACHER finds that although it is no replacement for a full-sized TV, the Walka 7 really adds value to a user’s life when on the move.

A few years ago DStv Mobile announced the Drifta, a mobile device that could pick up selected DStv channels and stream them to your smartphone, tablet, notebook or desktop.

The device was certainly innovative, especially considering the slow speeds and high costs of data in South Africa.

However, the device disappointed. There were very few channels available for Drifta users and, although there were no subscription fees for DStv premium subscribers, those without DStv had to pay a monthly subscription. It almost felt as if MultiChoice were merely offering this product to South African premium subscribers as a way to offset their massive monthly subscription fees.

Since then, DStv Mobile has released the Drifta USB, with more channels, the device was limited to desktops or notebooks with USB, and had no Wi-Fi streaming functionality.

Now, DStv Mobile is offering South Africans the Walka 7, a 7‚” handheld device. It eliminates the need for a secondary device like a tablet or smartphone, as it lets users watch TV directly on the device. We put the Walka 7 through the Gadget Five Question User Test.

1. Ease of use (including setup)

The Walka 7 doesn’t need any drivers, nor does it need any kind of setup. However, you do have to phone the Multichoice call centre to have the signal to the device activated. Once the subscription is activated, though, it will work the moment the batteries are charged and the unit is switched on.

Operating it, on the other hand, is a little confusing. It looks and feels like a 7‚” tablet and I found myself tapping on the screen to access different functions much like you would on any tablet. But, in order to keep the price as low as possible, the Walka does not have a touch screen. Instead, all the controls are crammed into the top right corner of the device, making it nearly impossible to use without first turning it around to find out what button you need to press.

More usefully, the Walka 7 includes a stand that lets you adjust the tilt angle of the unit if you’re not holding it.

The Walka 7’s ease of use and seamless setup all count in its favour.


2. General performance

The built-in battery will run the Walka 7 for around six hours, depending on the signal strength. This is more than enough time to watch a full soccer, rugby or cricket game and is also great for keeping the kids entertained while on a drive on holiday. The battery will also take three to four hours to recharge fully, but it can be connected to a computer’s USB output for trickle charging.

The screen, which offers a maximum resolution of 800×480, is still not the greatest of quality, but is a vast improvement on the smaller Walka. It doesn’t offer a wide viewing area, so it won’t do well when a few people want to watch it at the same time. That said, the Walka 7 is great for personal viewing while on the go.

Also, the bigger screen means that you should be able to get a bigger picture by changing the aspect ratio much like you would do on your LED TV. Although the Walka 7 offers this feature, stretching the picture just distorts it as DStv Mobile uses the DVB-H broadcast standard, at a resolution of 320×480.

I found that watching at the default 320×480 resolution was not perfect, with much of the screen pixelating or updating at a slower rate than the rest of the screen.

The Walka 7 did however offer decent sound: it was clear and didn’t distort even when cranked up full-blast.

Once the Menu, Channel, Power, Aspect Ratio and Volume buttons situated on the top of the unit were worked out, navigating the various on-screen menus was easy. It is very well laid out with the menu items easily identifiable.

The great battery life counts in the favour of the Walka 7, but the substandard screen an area where DStv Mobile should have focused will sometimes make watching TV on the move more of a irritation than a pleasure.

Score: 12/20

3. Does it add value to your life?

Since the original Drifta I have always believed that DStv Mobile has aimed the device at the sports enthusiastic. Although there are now various mobile bouquets available for the Walka 7, including a variety of news and infotainment channels like Discovery, there are no dedicated movie channels.

At home, the Walka will feel like a novelty device, but it really begins to serve a purpose when on the move. I should add that my colleague Arthur Goldstuck swears by it as an ideal way of following breaking news when he is working at his desk. So it does depend on your priorities.

Score: 16/20

4. Is it innovative?

The Walka 7 follows in the footsteps of the Walka 3.5‚” device and, though it offers a bigger screen, the controls are very similar and there are no additional functions that could be labelled as innovative. However, the idea of using the popular 7‚” tablet format for a mobile TV device does score points.

The idea of being able to extend your DStv subscription to any part of the city or country where there is a DVB-H signal represents a compelling value proposition for existing premium subscribers and, while not new on this device, continues to surprise, since it works in most urban environments in South Africa.

Score: 15/20

5. Is it value for money?

As a device to use at home, the Walka 7 is not worth the R900 especially considering that you can watch high-definition channels on a much bigger screen.

It is however a different story for when you don’t have access to a TV. Being able to watch that important rugby match or keep up to date with late-breaking news definitely warrants the R900.

The additional R50 that non-premium subscribers need to pay each month is also value for money considering the additional channels that have been added.

Score: 16/20

In conclusion

Total score: 75/100

Since the original Drifta was launched, DStv Mobile has introduced a number of additional mobile channels. While this is a step in the right direction, the Walka 7 is not a great device for watching TV as your main entertainment option. Those using the Drifta and streaming to a tablet will get better sound and a better picture quality, as their device will usually offer better specifications than that of the Walka 7. However, it is a fun option for keeping up with sports and news while in the office or on holiday.

Bose Portable: quality at a price

The Bose SoundDock Portable looks great and performs well, but SEAN BACHER finds the price doesn’t justify the better sound quality.

Since its inception in 1964, American-based audio specialist, Bose, has built a name synonymous with quality. Along with that, it has built a reputation of being more expensive than many of its competitors, but not deterring many from making the expensive investment. The mini sound speakers are quite often used in boardrooms, bars and restaurants around the world and offer crystal-clear sound that rivals most speakers twice their size.

Testament to the Bose sound quality is that it is used as the standard audio system in luxury cars like Audi, BMW and Mercedes, and according to Wikipedia, Bose products can be found in many military and NASA applications.

It is therefore not surprising to find Bose accessories compatible with smartphones. One example is the Bose SoundDock Portable. A portable docking station for iPhones and iPods that works off rechargeable batteries.

We put the Bose SoundDock Portable through the Gadget Five Question User.

1. Ease of use (including set-up)

Although the Bose SoundDock Portable, comes with instructions, they are not needed and in most cases, it will be ready to operate the minute it is removed from the box and an iPhone or iPod is plugged into it.

If the batteries on either the phone or docking station are flat though, the charger needs to be plugged into it before it can be used. You don’t need to wait for the batteries to charge fully before using it.

Bose has taken the minimalist approach with the SoundDock as on the right are two touch-sensitive Volume buttons and that’s it. No Power or other controls. The included remote is also very easy to use. It uses standard Play, Pause, Volume and Skip buttons, all well labelled.

The front of the docking station is made up of a silver grill, below which is the retractable iPhone dock. Although the casing around the connector is designed to accommodate an iPhone’s protective skin, it was not big enough to for the bumper I had on my phone, which meant I had to take the phone out of the case every time I wanted to plug it in.

On the plus side though, unlike many other portable docking stations, the Bose will charge a docked phone even if it is just running off battery power.

The Bose SoundDock Portable’s ease of use along with its elegant design cannot be faulted. But its dock connector counts against it.

Score: 18/20

2. General performance

The two front facing speakers offer crisp sounds and when the volume is cranked up all the way the SoundDock does not distort at all and is deafeningly loud.

At the rear is 3.5mm jack, allowing you to connect non-Apple phones, MP3 players and other audio equipment.

According to Bose, the 1 900mAh rechargeable battery pack will offer up to three hours of music at a maximum volume a different approach to rating battery life as most other vendors rate operating times at ‚”typical listening volumes‚”. I have been using the SoundDock on and off and not at full tilt for the past week without having to plug the mains adapter in yet.

This is however a good thing. Although the Bose SoundDock Portable is elegant and well made, Bose didn’t pay to much attention to the adaptor. It is a bit bigger than two cellphone chargers placed next to each other. It monopolises all the other electrical outlets, when plugged into the wall, meaning you need a dedicated plug for when you want to charge the battery.

The Bose SoundDock Portable provides a beautiful sound, its battery life is great, but the giant-sized charger is a complete let down.

Score: 12/20

3. Does it add value to your life?

Unlike many docking stations that are designed for bedside listening, the Bose SoundDock Portable is powerful enough to offer good sound in an average sized dining room or lounge.

Weighing in at just under three kilograms, it is not the lightest of them all, but the rear, recessed-handle makes carrying it fairly easy. (A carry bag is available as an optional extra.) Overall, it is a nice addition for a picnic or where an electrical outlet is not available.


4. Innovation

Sound docks have been around for years, and although the SoundDock offers superior sound, it offers nothing in the way of innovation. In fact, the lack of Bluetooth or any wireless connectivity for that matter is limiting.


5. Value for money

Much like the die-hard Apple Mac fans that will spend more on a product that performs much the same as cheaper alternatives, you get the same in the audio/visual world.

This becomes especially clear when reading the various reviews posted on the Internet. Reviewers either dislike the Bose SoundDock Portable due to it price, while others like it, saying the sound quality justifies the price.

But at R5 000 for a docking station I would have to agree with the former reviewers. R5 000 is ridiculously overpriced, even though it offers superior sound.



There is no faulting the Bose SoundDock Portable in terms of elegance and sound, but its clunky charger and high price are complete turnoffs.

Nokia Lumia 720: Well rounded: great battery

The new Nokia Lumia 720 has been punted as a mid-level phone. This means Nokia would have had to cut back on features and specifications to keep the phone’s price down. SEAN BACHER checks what’s missing.

For a few years, Nokia was almost forgotten in the smartphone market. This changed with the release of the N9, running its in-house developed MeeGo operating system. Sadly for its many fans, MeeGo was then summarily dropped. Instead, Nokia unveiled a range of high-end Lumia phones running the Windows 7.5 operating system and, finally, a second generation Lumia range running the Windows 8 platform. At the same time, the company targeted the entry-level market with its Asha feature phones, running the Symbian Series 40 operating system.

Between the top end Lumias and the Ashas, it has been quietly filling out its offering, The latest, the Lumia 720, is intended to be a mid-level phone with high-end features.

We put it through the Gadget Ten Question Task Test to see how it copes as a mid-level phone, and to find out what’s missing.

1. General look and feel (aesthetic judgement, differentiation in look and feel)

The Lumia 720 follows a similar design to its siblings in that it uses a unibody design, meaning there is no removable back plate or battery. Three virtual buttons are located below the screen and it has a Volume rocker, Power and Camera button on the right.

The plastic chassis has a rubber feel to it, which makes it easier to hold and less prone to scratches and dings. On the right is a microSIM card slot and at the top an SD card slot, both allowing for easy access.

The phone fits comfortably in your hand and is quite easy to operate with one hand.


2. Slippability (Weight and size, ability to slip into a pocket unnoticed)

Nokia has significantly cut down the weight of the Lumia 720, which comes in at 128g: the 920 hits 185g. Size-wise, it measures 128x66x9mm, making it a confortable fit for most pockets and its curved edges make it easy to lift off flat surfaces.

The phone cannot be faulted in terms of size and weight.


3. General performance (speed, responsiveness, multi-tasking)

Running the Windows Phone 8 operating system is a 1GHz Qualcomm dual-core CPU, which is complemented by a dedicated Adreno 305 GPU. The phone packs 512MB RAM and 8GB on-board storage. On paper, these specs are not too impressive, but in practice there is nothing wrong with them.

The Lumia shows no signs of slowing or freezing, even after numerous apps are opened. The active tiles update effortlessly and playing processor-intensive games like AE 3D Motor, which uses the phone’s accelerometers to guide a bike through traffic, does not jolt.

The 8GB of on-board storage is not that great, especially when movies and music start to fill the memory, but the Lumia 720 accepts SD cards, meaning that the storage can be beefed up to 64GB putting it on a par with high-end devices.

The phone performs very well, even with a lower-end set of specifications: the ability to install an SD card really is a plus.


4. Life as we know it (How’s the battery life?)

The non-removable Li-ion 2 000mAh battery is said to provide up to 520 hours of standby time and over 13 hours of talk time. Both of these claims are tall orders for most smartphones that typically provide just over a day’s usage before they need to be charged.

But, the Lumia 720 lives up to Nokia’s reputation of having some of the longest-lasting batteries found in a phone. Although I did not count the number of hours the 720 went without being charged, it was able to hold its own for over three days. In that time it was bombarded with new apps, was constantly being used for WhatsApp messaging and was also continually used for making and receiving calls. The battery went over and above what is required in terms battery-life on a current smartphone.


5. Vision of the future (picture, video and browsing quality)

The IPS (In Plane Switching) LCD capacitive touch screen measures 4,3‚” and boasts a maximum resolution of 480×800 pixel per inch. Although this is not the biggest, nor the clearest of screens, it was more than sufficient to view videos and images. In fact, the only time the sub-standard screen quality was noticeable was when the 720 was put next to its bigger brother, the 920.

Windows Explorer on the phone launched effortlessly and displayed all websites without any hassles: the pinch to zoom option came in very handy when inputting credentials to access a website.

The Lumia 720 uses a 6.1MP rear-facing camera, which features Carl Zeiss optics and thus makes images vibrant and clear. The front 1.2MP camera made a viable option for video calling and both record videos.

When making an entry or mid-level phone, manufacturers have to cut back on certain specifications to keep the price low. Even though the Lumia’s screen is not the greatest, it is more than adequate. But the oversized bezels around the screen count against the phone.

The bezels all around measured more than 5mm, which could have been converted into a larger screen.


6. Talk to me (quality of audio)

The Lumia 720 single loudspeaker is clear enough to hold conference calls, and is great for streaming music from TuneIn radio. No distortion was heard when the volume was cranked all the way up.

Overall, the audio quality is on a par with most other smartphones, but is not anything that will blow the user away.


7. Message in a bottle (range, speed and efficiency of messaging solutions)

Adding e-mail, Twitter and Facebook accounts is very easily done through the Account Settings function, but the phone streams all this content to a single hub, making it difficult to work out which message is from which account.

That said, individual apps are available from the Windows Phone Store that will present their relevant streams. Many of these apps can also be moved to the Home screen, and can be set to update on the fly, meaning that the latest content will be updated and automatically displayed.


8. Keep control (How effective are hardware and software controls?)

The physical buttons located on the right of the phone are all within easy reach when using the phone with one hand, and do not sit flush with the chassis, so are easy to identify in the dark.

The three virtual buttons at the bottom of the screen allow users to return to the Home screen, go back when in an app and quickly search the phone for a contact or app. Pressing and holding the Home button launches a task manager, from where apps can be closed and sent to the background and new ones opened.

The control buttons are very similar to other Windows Phone 8 smartphones, so the Lumia scores average here, too.


9. The new new (innovations, unique features)

On the hardware side the Lumia 720 offers no unique or ‚”wow‚” features, but a few of the preinstalled apps deserve a mention.

The phone is Office 365 ready, meaning that a user merely has to input his or her Office login details and is immediately able to view, edit and download documents from SkyDrive.

The Nokia Drive app contains most country maps, and a user merely has to choose a country, and the map is downloaded to the phone. Turn-by-turn instructions can also be downloaded and different languages can be chosen. Ever heard a woman giving you South African driving instructions in Chinese?

Then there is Nokia City Lens. Launch the app, calibrate it and point the phone down a street. The phone employs augmented reality and puts shopping, dining and points of interest on the screen with descriptions and contact details.

Although these apps are not unique to the Nokia Lumia 720, they count in its favour, especially when considering it is a mid-range phone.


10. The wallet test (Is it competitively priced?)

Coming at R5 500, the phone fits comfortably in the mid-range market. It also slots in well between the entry-level Lumia 520, which retails for R1 899, and the higher-end Lumia 820, which will cost R6 400.



Overall, the Lumia has a great set of features built into it. Its battery life is amazing and, even though the screen is of sub-quality, it is adequate.

Total score: 79%
