For those who like the idea of practically carrying a mini-notebook in their pocket, the E90 Communicator is one of the most comprehensive available. It won't appeal to everyone but despite the lack of TV-out and fax features, it is the best of business phones.

The BlackBerry Pearl 8120 updates last year's model in all the right ways and offers more than enough wow without being too flash.

The BlackBerry Curve 8310 adds GPS to an already enticing unit. Its only real drawbacks are the lack of Wi-Fi and 3G connectivity.

For those that don't need 3G or the Pocket Office applications you get with a Windows Mobile 6.0 device then the BlackBerry 8820 is a clear and highly desirable choice.

The Treo 500v aims to appeal to a broad audience thanks to its user-friendly menu system, a sleek design and a range of multimedia features. It's not perfect, but is definitely a welcomed entry into the market.

The JASJAM is a fair device with a generous features list, but a slow processor and chunky size dampen its appeal.

The Limited Edition Xda Atom Life adds the Windows Mobile 6 OS and a stylish white colour scheme, but nothing else has changed. Despite this, its still a very reasonable smart phone with a strong feature set.

The P1i is packed to the brim with features, and its only real downside is the unconventional keyboard, as well as an interface that will take some time to grasp. If you can get your head around each of them you're left with an excellent device on the whole.

The MOTO Q 9h's excellent QWERTY keyboard makes it ideal for heavy emailing. On the whole, this is a competent smart phone that's packaged in a nice design.

While it won't appeal to everyone and comes with a hefty price tag, the Flame certainly does an excellent job of providing a great multimedia experience, thanks to an on-board graphics processor and quality display.

The MOTOROKR E6 is a fashionable smart phone that includes A2DP Bluetooth, a 3.5mm headphone jack and performs reasonably as a music player, but potential business buyers will be deterred by a lack of other features

While it uses a technology still in its infancy, the HTC Touch is the beginning of the future of mobile phone interfaces. A lack of 3G connectivity and a slow processor are sour points, but the stylish design and touch screen are attractions.
