AT&T has seemingly stopped offering discounted tablets with two-year service agreements, according to details obtained by Engadget.  We’ve long said that carriers are silly to ask consumers to purchase tablets with the expectation that they sign a service contract.  Saving a hundred bucks or so up front has never been worth the price of climbing into bed with any wireless provider.   Of course, AT&T is still more than happy to hook you up with a tablet under their DataConnect and MobileShare plans.
