There's just so much you can do with this phone from an applications point of view. It should start hitting the shelves in Northern Europe in a matter of weeks now. If you want to know more about the phone... check out this multimedia presentation from Sony Ericsson or read a review from Mobile Review.
Some people are saying that the phone is too conservative in its styling, and will stay on the shelves. I hope they're wrong. I think it's one of the more stylish designs of phone I've seen in a while.
