This is the latest in the windows series, and as much as I loved "ME" I must say this package just blows it away! I signed up for the Microsoft beta test programme and I've been using the "profesional" version. As soon as it was loaded my system seemed faster and more stable - thanks to the "NT" arcitechture. The only down side of the "profesional" beta was the lack of drivers and support for some of my software - I'm sure this will be fixed by the release date ( or soon afterwards ). to sum up all the rock solid stability of "NT" but pretty friendly and fun to!!
