Personally I think your asking to much and in flight from reality. This is not how the wireless industry operates. I don't know any manufacture that offers big step upgrades.
It's a bigger upgrade then going from a 600 to a 650, I also think it's on par with the rest of the competition. Now if they don't release it till Q4 then it might fall behind the competition.
I'm happy with the specs and if there was only one thing more I could squeeze out of it that would be GPS, even a carrier based GPS would be fine.
O am sorry, this is for people who are disappointed with the specs...........A thousand apologizes.
