The N800 is Nokia's second generation Internet Tablet, replacing the Nokia 770. It offers some serious improvements in the CPU, RAM and looks departments while adding $50 to the price. The device features a phenomenal 4" 800 x 480 color touch screen, the Opera 8 web browser with Flash 7, a webcam, WiFi 802.11b/g, Bluetooth, email, PDF reader, IM and a slew of other apps. It's not a PDA and it's not a phone, rather it's meant to bring the Internet along with you most anywhere with a desktop-like experience. And yes, it fits in a roomy pocket and it runs Linux.
Besides browsing the usual websites, the N800 can also be a great device for playing browser-based Flash games that are optimized for it. Notable websites include http://www.gamoku.com - they provide browser-based Flash games optimized for mobile devices like the N800 and Pocket PC.
