I'm currently on AT&T but don't have a smart phone nor contract. Just month to month, and while I want to stay with them since they have the best coverage in my area, it seems this is just screwing over the customers who didn't get an iPhone or unlimited plan prior, even more.
I really want an Android phone and am willing to pay for an unlocked HTC one, but I wouldn't be able to get an unlimited data plan. However I can always sign up for Verizon and get the same HTC phone, which AT&T doesn't even offer and get an unlimited data plan. Hell I can sign up right now for an iPhone with Verizon and get unlimited too. Not so much from AT&T.
This makes absolutely no sense if your goal is to retain customers. If I didn't hate Verizon so much I would have probably already signed up.
*sigh*
