I had one pre-ordered at HMV but backed out. However, I was with my friend who did buy one and set it up. Firstly, If you have your tv at a reasonable volume, and especially if you have a game installed while playing, you won't hear the 360 running. There is definite noise, being the giant fan on top and the disc drive, but it is substantially reduced. There are plenty of USB ports, no memory unit slots, and that Kinect port. The wireless n onboard card is excellent, but it all depends on personal network setup. Some sort of function really should have been added a while ago. I'm not a fan of the angular looks and glossy-dust-magnet finish but that is personal preference. It is disappointing that they have re-designed the hard drive slot, but the new ps3-style insert is nice.
I think that is about everything. Nice, but not essential.
