Right on cue , Nokia's WiMAX-enabled N810 Internet Tablet has surfaced at CTIA 2008, and yep, this critter is destined to go on sale here in the US of A this summer. Beyond that, you'll notice the familiar 4.13-inch touchscreen, slide-out QWERTY keyboard and even a built-in webcam for video calls, Mozilla-powered browser, integrated GPS / media player, 2GB of internal memory and a microSD expansion slot. Heck, Nokia even touts this thing's ability to "access the Internet over WiFi or via conventional cellular data networks by pairing to a compatible mobile phone via Bluetooth technology." Also announced today is the freshly updated OS2008, which includes an enhanced e-mail client, support for Chinese character rendering in the browser and RSS feeds and "Seamless Software Update functionality" to boot. Needless to say, said OS will come standard on the currently unpriced Nokia N810 WiMAX Edition -- which is scheduled to land wherever WiMAX connectivity is available -- but existing N810 / N800 owners will also get the OS upgrade free of charge in Q2.
