I'm in a 4G area (actually it was the first 4G area in the country at one time) and until it is reliable and 3G is no longer tiered pricing, the wired connections won't go away.

I'm really looking forward to a world of reliable 4G everywhere though. It's certainly not here yet...

Snippet:

Greensboro, Winston-Salem and High Point are among the first cities to enjoy 4G wireless connections from Sprint, the first national wireless carrier to test, launch and market 4G technology.

We have an abundance of 4G wireless available here but it is not 100% reliable and certainly not mobile - if you move out of the 4G strength of signal area it drops to 3G automatically and that has tiered pricing - it's not unlimited for one cost.
