I plan to stick with my 8320 Curve until I can pore through all the initial reviews. I'll make my decision whether or not to buy the new device based on those reviewers' impressions. I've heard battery life is going to be a problem, and that makes me a bit hesitant to run right out and get one. Definitely interested, though.
I am going to wait and see if they come out with a curve replacement seeing this looks to be an 8800 replacement to me. Remember how the curve came out shortly after the 8800. Knowing me, I won't wait.
