I just got one yesterday. I moved up from the 8330, so the OS7 is freakin awesome!!! I am very happy with it so far, I've been playing around with it all day today. One thing I haven't gotten used to yet is that the keys are hard to press. I'm sure I'll get used to it eventually.
I'm loving mine, coming from a Tour 9630. Though, mine keeps rebooting on it's own if I do heavy internet. i.e. streaming videos, downloading music, and/or loading 2 webpages (tabs) at once. I think I may have a bad one, trying to get Sprint to swap me out for another one....other than that I love it!
