The Nokia N81 comes in 2 types, an 8GB version and a smaller version but with a MicroSD slot to increase memory should you so wish. The phone itself brings nothing new to the world of mobile phones but what it does do it does well. Most noticeable about the phone is the Navi-Wheel in the bottom centre of the handset which can be set to work as a kind of small touch panel making navigation through the phones menu far easier and being especially useful if you have a lot of multimedia to flick through. Around the Navi-Wheel are the controls for your media such as play/pause etc. The phone is not light at 140g and measures 102mm x 50mm x 17.9mm which is rather large for a mobile phone but makes use of a sliding keypad to keep it as compact as possible.
