Nokia N800 WiFi Portable Internet

You get about 3 hours of solid surfing via wifi, and about 5 hours via bluetooth. If I leave the phone in standby I can still be alerted of instant messages via GAIM and the power will last for days. I go to work with a full charge and leave work with a full charge. Installing programs, such as GAIM is a snap once you add the repository urls to your application manager. Once you do, the system maintains a catalog of all of the available programs and you simply click to install a ton of programs.
