The Omnia is Samsung’s attempt at pushing Windows Mobile as far into the background as possible, but it’s certainly not perfect. With more tweaking to the TouchWIZ interface and a bit more speed, this could potentially knock the iPhone off its perch. As it stands though, it's an admirable handset without being outstanding.

The AVIC-F500BT is a unique but welcome addition to the navigational market. This is the perfect device if you want to add the latest in navigation and entertainment to your vehicle without altering your existing stereo.

The much-hyped Touch Diamond had plenty of potential, but ultimately it is a hugely frustrating phone to use. A great display, stylish design and reasonable browser are let down by a sluggish and slow user interface. Unfortunately, the great eye candy of the Diamond isn’t enough to push it over the line.

The i780 improves the usability of an otherwise regular Windows Mobile 6 device by offering a redesigned home screen and an optical joystick.

Despite the N82's tiny keypad and questionable all-plastic design, it remains a solid handset boasting a long list of features.

The RIDER 2nd edition offers several significant improvements over its pioneering predecessor, including a superior headset and bike mount. While a few flaws remain, it has managed to avoid most of the key obstacles that hamper other units.

There have been some good improvements to the Mio A702 over its predecessor, the A701, and while the navigation wasn't overly effective, it is a hybrid device and can't be expected to do everything perfectly.

A larger screen enhances an already enticing package. The N60i is an excellent GPS, with a great user interface and quality maps.

The Navigator 7000 is outstanding for road safety thanks to its "Road Sense" subscription, but its navigational performance could be improved.
