Toshiba is developing tablets of its own to get into the category being established by the iPad, the company's US notebook lead Jeff Barney said in comments today. He anticipates a line of devices to arrive either by late this year or early 2011. No details were given to Fortune of what the devices would involve, but Barney acknowledged that Toshiba would likely have to move fast to claim a stake in the market before Apple and others risk crowding it out.
