Those looking to benefit from the flexibility and accuracy of smartphones that offer a more capable operating system and display may become frustrated by the M10 but, if satellite navigation is a primary concern, there's plenty to like.
Excellent GPS capabilities; good quality display; 3.5mm headphone jack; good battery life.
Rather outdated and sluggish operating system; touch-screen accuracy issues around the edges of the display; resistive rather than capacitive screen
£ 300 SIM-free

MP3 players have suffered in recent years owing to the ever-increasing flexibility of the mobile phone and, if partnerships like Garmin-Asus are anything to go by, the in-car GPS should be heading the same way.
The Nuvifone M10 is a Windows Mobile smartphone that looks to combine the strengths of Garmin and Asus to produce an all-rounder that tips its cap firmly in the direction of satellite navigation.
Of course, most modern smartphones now offer some kind of navigational aid but, while this is often seen as an addition to the core functionality of a communications device, the M10 seems to have done it the other way around.
The handset is based on Windows Mobile 6.5, which may not prove too popular with those used to the faster, more flexible and more intuitive approach taken by alternatives such as Android and Symbian.
But this isn't something that should put off users who are happy with a less versatile environment that's perfectly capable of handling the core functionality of the phone.
Garmin has opted against capacitive technology for a cheaper, less versatile 3.5in resistive display. This is a bit of a shame considering the benefits of multi-touch in zooming around a map but, with a healthy 480 x 800 resolution, we're not going to get too hung up on it.
The M10's accuracy as a touch-sensitive screen is reasonably good, but lags behind some of the big hitters in this market as it occasionally misinterprets an action or fails to register a command.
This doesn't happen too often, but more dextrous individuals who expect to fly around menus at speed will find it lags a little at times, and buttons or icons placed at the edge of the display can be awkward to hit correctly with a finger.
There's a built-in stylus to help improve accuracy, and for the most part buttons are large enough to compensate for less nimble digits. Aside from the main display there are three soft-keys for accessing the main menu and dialling or hanging up a call. These can be a little unresponsive, though, and are no substitute for raised tactile controls.
In terms of quality and clarity, this is an excellent display that recreates vibrant colours accurately and cleanly, and is capable of an impressive amount of fine detail thanks to the relatively high resolution.
This is particularly evident with the built-in 5-megapixel camera, and the high refresh rate of the screen makes it a joy to snap photos and 800 x 480 30fps video. The shutter response is extremely quick, and photos display in under a second, although, as with most cameras of this ilk, quality is compromised considerably in dimly lit environments partly due to the lack of flash.
The only real qualm we have here is that the screen can actually be a little misleading as to the quality of a picture. On transferring images to a computer we noted that colours weren't as vibrant as they initially appeared, and a bit of work will be needed to enhance these to a desired level of quality.
