Nokia today introduced the Nokia N810 Internet Tablet, signifying a new phase in portable internet communication. Sporting Bluetooth 2.0 and Wi-Fi 802.11b/g connectivity, a slide-out QWERTY keyboard and a full-fledged web browser, there’s only one thing missing: WiMAX. However, a WiMAX version of the N810 will be coming next year. In the meantime, the N810’s Wi-Fi connectivity will provide Internet access through hotspots as well as home and office networks, including via Boingo Mobile. Applications compiled for the previous two Internet Tablet models will not be compatible with this one. This hurt the N800 a lot too, because most developers didn’t care to re-compile their apps as they kept their N770. Hopefully this is the last time Nokia breaks compatibility.
