The N810 features, Wifi, Bluetooth, GPRS and a full slide out keyboard. The screen has a good looking resolution at 800×480, but the thing that grabbed my eye was this nugget.
The Nokia N810 is powered by maemo Linux based OS2008, updatable also on the Nokia N800, the previous internet tablet generation hardware. The Nokia N810 features a highly customizable user interface and contains various novelties such as a Mozilla based browser with Ajax and Adobe flash 9, Bluetooth headset support as well as enhanced video and audio features.
It is expected to start shipping mid November with an estimated retail price of 479 USD (excluding local taxes).
You can see some pictures of the new N810 over at the Nokia Press Site.
