The Nokia N810 is a PC in your pocket. It has many built-in features such as GPS, wifi, bluetooth, and a web cam. It's a great device for checking emails, browsing the web, and doing just about anything else you could do with a full sized computer. It features a very vibrant touch screen display and a full slide-out QWERTY keyboard for input. It uses a Linux based operating system and has thousands of applications available for free. See the video reviews at the bottom of the page or my review of the device here for further information.
