In regards to the AT&T data plan changes, if it is successful, I see other carriers following suit. However, we'll see how consumers take too it. Saving 5 dollars a month to get 40% of the data you were getting before doesn't sound like a good deal to me. I am sure most of AT&T's users don't go over 2 GB. But, I would imagine this change also goes for air cards. In that case, I could easily see users going over the 2GB limit.
While AT&T saves you 5 dollars a month and cut the data by 60%, Sprint raised their rates by 10 dollars for the EVO and made it truly unlimited with no cap (for 4G).
The difference between stupidity and genius is that genius has its limits.
When you take things for granted, the things you are granted, get taken.
Even a mosquito doesn't get a pat on the back until it starts to work.
Too many people miss the silver lining because they're expecting gold.
