There are lots of features which you cant explain in screenshots, you just have to try it to see it. Such as aero shake. Shake one window, the rest minimises. The traffic was grand when downloading, they removed the "only first 2.5million people get to try it", so you have to 2 weeks if you want it. The licence expires August first, but RC version will be out by then. Then I'll get the real version for free because of MS Ireland TechNet. (I got Vista free)
