Previously, the only Dell Streak or Mini 5 (whatever you want to call it) was the only Android tablet Dell had in the works coming to AT&T, possibly with an off-contract model as well, this summer. But look, now the Mini 5 has siblings! Just as Dell stated not too long ago, there would be a family of Dell Streak tablets running Android. The Dell Streak 7-inch is well, a 7-inch version of the 5-incher, and the 10-inch is just well even, bigger. There’s not much else known about these slates, but we do know the release dates. Expect the Streak 7 to come out at the end of this year, and the 10-incher early 2011. It is agonizing and frankly weird that the direct iPad competitor in the Dell line will come out in 6+ months from now, but it looks like that’s what Dell has in mind. Oh well.
