video calling chews through batteries like no tomorrow, something Europe and Japan learned the hard way, while adding very little extra value (not saying there isn't a need for it, but the majority of video calls can use just plain audio with little or no difference). Personally i dont think cell phones are a good medium for video calling, your going have to find a new way to hold your phone that keeps you in the picture while ensuring you dont block your view of the real world and get a blue tooth head set or end up shouting everything at the phone
just my 2 cent
