The Wall Street Journal has picked up on the Blackberry tablet rumor that we heard about last month from Boy Genius Report. From the way the WSJ article is written, it doesn't sound like they actually have any more information than BGR. Heck, that might even be their source.
RIM is also experimenting with a tablet device to serve as a larger-screen companion to its BlackBerry phone, say people familiar with RIM's plans. That device, which is in an early stage of development, will connect to cellular networks via a BlackBerry phone, these people say. It could come out as soon as the end of the year, these people say.
