But I've/we've all wondered why 3G costs $130 more. I've heard estimates of the parts being $10. Okay, perhaps $30 for the whole module, backshell change, whatever.
So, $100 to AT&T as payment for 'lost' revenue for no monthly contract to make up for the cheap data prices makes sense. Maybe that deal was only for one year? So, after all the newness wears off, the first iPad refresh (next spring) will give us one line, all with 3G, and a cheaper price (essentially free 3G radio, as it should have been now).
Of course, I'm making all this up. But it covers all the facts. It never made sense to have two kinds of iPads, especially when 3G was optional. Unless there was a good monetary reason for it. 😀😀
