As part of their, "We Survived the Apocalypse!" sale, AT&T is offering an instant $100 off any Tablet, including iPads, when you signup for a 2-year data plan. You'll wind up spending more on the data plan over the 2-year timeframe, of course. But, if you'll be using a monthly cellular plan anyway, it's worth a look at this deal. Offer ends January 10, 2013.
