Note: MobileWhack has a nice review of the Linux based Nokia N800. After reading through it sounds like this has all the bells and whistles of a portable handheld computer. Only issues seems to be a recurring one of handwriting recognition/ virtual keyboard vs. built in hard keyboard. Personally think until they really advance the software in that area, keyboards even if they are small are here to stay.
Review:
The Nokia N800 internet tablet features a large 4.1-inch 800x480 touchscreen display, which displays both text and pictures very clearly. Other features of the tablet include WiFi connectivity, Bluetooth, a mini-USB port, and a 3.5mm headphones jack. It runs off a 320Mhz TI CPU, and 128MB RAM, and includes 256MB of flash storage and two SD slots.
Alongside the top of the tablet is the on/off button, zoom buttons, and microphone. On the front of the Nokia on the left side next to the screen, is a a 5-way joypad as well as three other buttons - one for closing applications/windows, one for application menus, and another button for task switching.
At the bottom of the tablet is a kickstand which folds out to prop up the device, which is great for watching videos on.On the left side of the tablet near the top is a really cool pop-out VGA video calling camera. When not in use, it retracts nicely inside the Nokia.
Press on it to pop it out, and then you've got a nice little camera which because it is so discreet, it looks like a spy cam. Inside the box I found the tablet, a spare stylus, stereo headphones (w/ call answer/drop buttons and mic), a cloth protective pouch, a 128MB SD card with case, a USB cord, and a power adapter. The stylus is just the right weight - not too heavy, but not too light - and slides easily into its storage slot on the back of the tablet.
