What are you really going to use that speed for on the iPad 2? Web pages open the exact same as they would on 3G. Seeing as how there are bandwidth caps in place, speeds like this wouldn't really help the iPad at all. More speed is always great, but on the iPad, how would you really utilize it?
I don't use my phone much, so my battery is good.
But how much video are you actually watching away from Wi-Fi? I mean I see your point, but overall, seems a little overkill.It would be nice for watching videos online without constant buffeting.
