I think what most of you are missing is that many cellular providers provide only a fixed number of bits every month.
If you go over you face a large penalty.
So, this isn't such a big deal for those with the wifi version and virtually unlimited bandwidth at home.
It's a problems for those use those fancy new 4G LTE plans (like mine) that will use up your allocated bits much faster.
You'll be able to load those large images faster, however, that counts against your monthly download limit.
Something to think about as unlimited plans are rare.
Verizon just sent me an offer for the new iPad.
The available data plans are:
2GB for $30
5GB for $50
10GB for $80
Those on the 2GB should consider at least consider this point.
