OK, Dell Streak fans, this is your chance to speak up. No one? OK. After Dell stopped selling the Streak 7 tablet, essentially giving up on the Android tablet scene in America, many believe that it's preparing to transition to Windows tablets. A new 10-inch Windows 7 slate is already coming, and Windows 8 tablets should be available in late 2012 or 2013. Dell didn't confirm any definite plans. But either way, Lenovo appears ready and willing to become the PC manufacturer with the greatest presence in the Android tablet world.
