When you first pick up the 5800, you'll be surprised to feel it's nowhere near as wide as many of its competitors, it really feels like a regular Nokia candybar, despite the big screen and lack of keypad.
This is a considerable advantage when looking at the wide bodied iPhone 3G or Samsung Omnia, it also feels well-built and the 109 gram weight ensures it feels properly planted in your palm.
With Symbian onboard, the 5800 XpressMusic is a proper smartphone too, with all of the downloadable software and customisation this brings with it. No matter what you want to do, there will be an app for you.
This version of the operating system has had an overhaul so it can be used on a touchscreen phone and it works very well, with Nokia implementing a 'double click' system to decrease the likelihood of making a wrong choice.
