I updated my Desktop Screenshot showing Windows 7 running in Virtualbox. It runs incredible. I even dropped it on an old box with an AMD AthlonXP processor, 2GB DDR 400, and an nVidia 6200 series card, runs smooth like butter baby. Incredible and feels a lot like Linux. The tale of the tape remains to be seen though. Wait and see what folks say about the final version once it has been purchased, installed, and ran for a month.
