W7 will prove to be the downfall of M$ even more than Vista did. There is no must-have killer app that necessitates "upgrading" from either XP or Vista. There is no massive performance boost, compatibility or stability increase. All you get is a revised interface to relearn, some new icons and a lighter wallet. Vista was the lid on M$'s coffin, W7 is a nail.
The age of freeware is at hand with Linux, OpenOffice, StarOffice, etc. The age of M$ is over. Only a fool would plunk down money for this crap. Especially when they already have reliable, stable software like XP.
