According to the NY Times, T-Mobile is planning a push further into the home with an Android-based home phone and a tablet computer based on the open-source OS:
T-Mobile plans to sell a home phone early next year and soon after a tablet computer, both running Android, according to confidential documents obtained from one of the company’s partners. The phone will plug into a docking station and come with another device that handles data synchronization as it recharges the phone’s battery.
A T-Mobile spokesman, Peter Dobrow, declined to discuss the specifics of any future products but confirmed that T-Mobile had plans for several devices based on Android.
This strategy appears to be an expansion of the company's T-Mobile @ home strategy. Incumbent landline carriers AT&T and Verizon have both introduced more advanced home telephones with integrated touch screens and limited Internet access to make their landline services more compelling.
We can probably expect to see a range of interesting Android mobile computing devices, which are not primarily phones, in the next year.
