The third generation Internet tablet from Nokia bears a great deal of similarity to the N800 it replaces. But it adds two key features: a GPS and hardware keyboard. This handheld computer has a fantastic web browser with support for Flash 9 and AJAX, email and RSS. It weighs 8 ounces and is as big as a large-ish PDA. Other features include a 4.1" touch screen, 400MHz processor, a Linux-based OS, Bluetooth, WiFi and a PDF reader. It's not a PDA and not a cell phone, but rather a mobile Internet device, media player and a GPS.
