Yes, I have it, been using it for a few days now. Feelings are kind of mixed so far. I seem to be having issues that I had with the original sidekick. My signal goes in and out more often and when it goes out I have a hard time getting it back, could just be the area but I don't recall having those problems with the other SK II.

The music player is pretty nice, it plays mp3's and sounds really clear with head phones.

The new track ball is so much better than the wheel on the previous models. Navigatoin on web pages is easier and you can open folders in mail or move through applications by scrolling left or right now which is cool.

I hate that none of the ring tones I had on either my Razr or my SK II are not available with this phone.

The keypad feels a bit nicer. It was weird at first but I really like it now.

One new feature, I guess they put in to extend battery life, I don't like too much. The screen goes blank after a period of time and the track ball will blink green when this happens. I've been so used to haveing my old phone on silent and when I would see it blink I knew I had a message or something. So seeing this is slightly confusing.

That's all I can think of for now.
