We've been waiting for Nokia to kick start their touch screen phone offerings, and we mean something more serious than a touch UI plastered on top of Symbian S60 like the N97 and Nokia 5800 XpressMusic. That phone is finally here in the guise of the N900 running Nokia's Linux-based Maemo 5 OS. That OS is pretty impressive, mighty finger-friendly and fast. An ARM Cortex-A8 CPU with graphics acceleration helps keep it quick and there's plenty of RAM and 32 gigs of storage too. The N900 is an unlocked GSM world phone with 3G HSDPA on the 1700 and 2100MHz bands. That means 3G speeds on T-Mobile's US network and 3G in Europe. The N900 has a top notch 5MP camera with a Carl Zeiss lens, WiFi, Bluetooth and a GPS too.
