Count me in as one of those bitter old men (if you can be an bitter old man at 30) about this whole AT&T rate change cluster. First, let me say that I see the upside to it. Limiting data usage will probably increase network stability across the board. From my perspective, I could care less, as my service in Albuquerque is outstanding (for both my iPhone and iPad), but, as I said, I see the upside. For me, though, one of the main selling points was an unlimited data plan that could be turned on and off. I'd say 95% of my time, I've got WiFi access, and that's all I'd need. Its when I travel, which is every couple of months, that I looked forward to turning on the UDP. Now, I won't have that option. Based on their philosophy with this whole change, I don't see why AT&T couldn't offer a $50-$60 UDP with the same ability to turn it on and off on the fly. The "superusers" would pay for that right, and AT&T could invest more into their network infrastructure. (On a related note, I think its bad pool for people to blame these so called "superusers" for all of the problems. If AT&T sells unlimited data, they need to have a network that can handle such loads. Period. From my perspective, AT&T couldn't handle the massive influx of iPhone users, and blame the "superusers" for the network trouble that iPhone and its many users, have created). But to change that plan, and take away the main selling point for my upgrade from a WiFi to a 3G model less than a month after its release? Just another in the long list of reasons that I'll be moving my cellular service away from AT&T later this year, iPhone 4 be damned.
