I've been running windows 7 on my machine for 3 weeks as my main os. Its a lot snappier than vista, which is saying something since I have a phenom 9750 and 8gb ram so vista is pretty snappy.
Driver support is excellent for a beta (heck its better than full os' I've had in the past). The new preview features on the task bar are excellent especially when you have upwards of 10 windows open (IM notification in particular).
My only gripe is they still haven't put extra taskbars in for secondary/tertiary displays and they've gotten rid of the vista networking icon from the task tray.
