So many things, but to just pick a few.
This will be my wife and I first Android phones and with the fact that I am gone from home for weeks at a time, the video conference will be the feature I am most excited about. To be able to talk to my wife and kids on the phone with video will be amazing!!! The screen size, speed, 4G and so on, but purely being able to see my wife and kids faces while I am on the road will be a massively used feature. Can't wait for June 4th (well June 1st to win one hopefully)
