I've been thinking about getting a Bionic since it was announced in Jan. But recently I'm torn between it and the X2. Most of my data usage is in areas with wifi, so I'm not sure its worth spending money on 4G. Been holding off on my upgrade since Dec and my contract ended last month. I have a D1 now and love it. I can't imagin how much better a faster device will be. I would like to hear some thoughts about what others think or are planning to do. Also, I'm interested in some opinions of users who were formerly on 3G and are now on 4G. It it a noticable difference? Is it worth the lesser battery life and larger bill?
