I use 3G video calls all the time. Sure you can say it is video chat, but the point is, I choose a contact, make a call that contains video over 3G. Technicalities will have people thinking that the above isn't possible on the N900. The other phones like the Sprint 4G and MyTouch 4G do the same thing, use a 3rd party app (Qik) to video call/chat. It just so happens that the N900s 3rd party apps are GTalk and Skype.
