I must be missing something on the release of this phone. I have heard (not sure if its true or not), that this phone is a replacement for the 640. It has a smaller screen, a less powerfull processor, a smaller battery, a lesser camera, etc and its going to cost more. I just don't get it. Would someone enlighten me as to how they can try to see this as a replacement for the 640. I really didn't think the 640 needed replacement. Too me the 635/640 have been the two best things Microsoft/Nokia has done in the last year, leave them alone.
