Nokia N800 is a great gadget. Unlike other products from Nokia this is an Internet tablet. You will not find a phone integrated with this device. And it is quite noteworthy that this device is powered by Linux. Obviously this is an upgrade for the Nokia N770 which could be considered as the predecessor of N800. I was first informed about the device by Bud, then I decided to order one of these beasts with the initial payment of Google Summer of Code program.
What attracts me to this device is its UPnP support, High-resolution touch screen (800 x 480 pixels) with up to 65,536 colors, Wi-Fi, Web cam. You can get more details by referring to the spec. How ever Nokia claims that this device is powered by Internet tablet OS 2007, even though this is Desktop Linux. So don't get fooled by such claims. The other interesting thing is that you can write your own applications using maemo framework. If you are not interested in developing your own application like me, then there are lot of ready to install apps at garage.maemo.org. And Ruby fanatics now you can even install Ruby on Rails.
The only drawback I found in this device is lack of phone. Apart from that rest of the features really satisfies me.
