See ya AT&T (eventually)
I guess I'm in the "lucky" position of being grandfathered in for the next year and 8 months, but if these plans are still in place when my contract is up, I'll go elsewhere. I don't use that much data (less than 2gb for sure), but it's the principle of it. Hopefully one of the other wireless companies are smart enough to take advantage of the situation and steals a chunk of AT&T's customers.
So, with this plan, you'd be saving $100 over the remaining length of your current contract, but you'd leave for another carrier, on principle? I can see why data whores would be upset, but I don't understand your complaint.
