Motorola's earnings call that he "sees good reason" to eventually release an entire family of tablets at "different multiple different display sizes and price points." Specifically, Jha mentioned 7-inch tablets, and later said that consumer demographics like kids, teenagers, and "women" want different things from a tablet than enterprise and professional customers -- which sounds suspiciously like Jha doesn't think women want a single device for work and home, but we'll give him the benefit of the doubt, since he's not always the smoothest speaker.
As for the Atrix, Jha simply said that "you will see our diversity in the retail channel as well with other carriers in the US," which certainly sounds like it'll hit other carriers once the AT&T exclusivity runs out. How long that exclusivity is, we don't know -- but keep in mind that the Droid Bionic is very nearly the same phone, so there's a chance a software update will bring that sweet docking action to the red side of the market in the future. And if not, we're sure the hacking community will have it covered.
