As a phone however, the O2 stumbles slightly. While its audio quality is good, there's a noticeable amount of echo during calls and no matter what we tried with the volume controls, we were unable to get rid of this feedback. This is disappointing ...

The O2 XDA Atom Exec is a super-fast PDA that's very easy to work with, however echo feedback during calls stop it from truly excelling as a primary phone.

The only real issue with this HP is that the 3inch screen, though it is physically big offers a resolution of only 240 x 240 pixels, which does make things look slightly cramped.

If you liked the older hw6515, you'll love the hw6915 thanks to its improved performance, top-notch GPS and significantly more useable keyboard.

The only feature we really missed on the Eten was built-in WiFi support. As it's a relatively high-priced device this is a surprising omission.

Considering its price, the Eten's lack of WiFi is surprising, however its built-in GPS feature still makes it a solid buy for those interested in exploring the Emirates.

Our only real niggle with the Ming is its rather basic 8Mbytes of on-board memory. This can be filled quite quickly with just a few photos and files and though this can be expanded using a Micro-SD card, considering its price we expected more.

The Motorola A1200 is a very stylish smartphone that lets you retain your fashion status and get work done at the same time. At $544 it's reasonably priced too.

As with the Palm Tungsten E2, the E61 can be sluggish when launching and switching between apps and doesn't offer a digital camera.

The E61 is bred for push e-mail and, as is typical of Nokia's mobile products, it's one of the easiest and most intuitive smartphones here.

The most interesting app here is Voice Assist. This is essentially a voice dialing program, but unlike those offered by vendors such as Nokia, you don't need to 'train' the phone with your voice before it understands you. Instead, you simply pronounce ...

The Samsung i320 proves that it is possible to have a quick, slim smartphone with bags of features at a very attractive price point.

One big advantage the clamshell design does have, though, is the ability to dial and text using a regular phone keypad - very like the Razr's - a boon to users who miss such functions on a PDA. This may well be the Smartflip's target audience - people ...

If you're a style-conscious user, this will float your boat if you can afford it.

At best then, the P50 is an adequate - if overpriced - PDA; the only truly neat addition is the remote controller - good for sneakily changing the TV channel. Check out something like the Sony P910i or the Eten M600 ahead of the P50 - you'll get more ...

Employs the tagline 'Don't Work Harder Work Smarter'. Our advice is to shop smarter - elsewhere.

Add to this the slightly grainy-looking screen and its relatively low resolution, and the Typhoon comes across adequate rather than exciting. It's relatively cheap though, so if you need a PDA on a budget, this may be for you.

Pretty cheap and basic, the Typhoon is reasonable for those on a budget, if you don't mind the niggles.

The Samsung player refused to sort album songs by track number, and Windows Media Player insisted on buffering songs before playback - not the end of the world, but a pain if tracks flow into each other. In all, quite basic and for US$650 there are ...

Some nice touches but its style and performance just don't justify the hefty price. Shop around.
