N 810

The N810 may come in the same size box as a mobile phone, and it might have "N series" celebrated on the side, but don't be fooled into thinking this is minimally a Nokia with a big screen and slide-out keyboard - it's anything but.
It doesn't have mobile data capability, for starters. You need a Wi-Fi network or a Bluetooth connection to a mobile phone if you want to access the internet. The N810 doesn't run Symbian's S60 OS, either. Instead, you'll find Maemo, a Debian-based Linux variant.
