People here are so brainwashed it's amazing.
Apple forced AT&T to offer unlimited as part of being an exclusive carrier. It was back at a time when data was 2G and a heavy user used 20MB a month. People who signed up felt they were entitled to lifetime unlimited data at fast speeds for that date...even though the speed/use of data has grown exponentially. And how dare AT&T not build infrastructure off that same $30 to pay for ever increasing data needs.
Every rational person who owned a business would think the exact same way. The 'all you can eat' model for data consumption doesn't work in the cellular world which has a much more restricted 'pipeline' that other internet service options.
Of course a lot of the vitriol is because it's AT&T. If Apple ran a cellular service and Steve Jobs said this last year, people would be fawning over how profound it was.
Well, you're not that unbrainwashed, either.
AT&T has a 5GB cap. Let's examine 14.4MBit/s on the iPhone 4S here, and let alone LTE on the iPad.
14.4MBit/s = 1.8MB/s.
5000MB / 1.8MB/s = About 15 Minutes.
You can use that connection 15 minutes of a 30 day month. That's approx. 0.025%.
Seriously?
Also, within those 15 Minutes, it works fine. It would work fine another 15 minutes tomorrow. And every successive day. Until proven otherwise.
15 minutes of a day, that's 1%.
Those 5GB are hilarious, if it were money that would be a nickel, at 14.4MBit/s.
A realistic cap would be in the 50-100GB range. Who would use it? No one. Would lots of people even surpass the 5GB mark? Probably not.
But: Would you cancel your U-Verse account? OF COURSE!!11
And there lays the problem about this whole "The technology can't support it" crap. For some strange reason, Sprints network does support unlimited bandwidth for everybody. Why? Because the customers who cancel their DSL line for an LTE stick won't be their own.
