Although this hasn’t officially been announced on TechCrunch, Michael Arrington announced on the latest Gillmor Gang that on December 29th Prototype B of the TechCrunch Tablet was finished.
There wasn’t a lot of details mentioned about the new prototype but Arrington did say that the tablet has a 12″ touchscreen and was capable of playing back Hulu and YouTube videos open across 3 tabs in a browser (presumably Firefox) with no skipping.
Arrington also mentioned that the device costs about $222 to make and is “pretty fuckin’ kickass.”
