Hi all, I am in the market for a new Droid, and was wondering how 3G compared to 4G compared to WIFI. The reason I ask is a HUGE majority of the time I would be using data, would be at home, with my WIFI connection. If it is pretty similar, I might just wind up getting something a little cheaper, like the Incredible 2 or the Droid X 2 when it comes out.
