I've been testing out Windows 7 Beta build by beta build and I'm telling you follks, XP is great and every one knows it, Vista sucks for reasons everyone knows and Windows 7 as it is now I feel is set to be the new XP.
If you can, get Virtual PC, download a copy of Windows 7 and give it a shot, you really won't be dissapointed.
Jumping on the bandwagon a bit? Most operating systems are poor when they first come out, XP was until SP2, Vista, imo, still is because it wastes so much performance - And I have used vista, I only just downgraded to XP. I won't put Vista back on until some SP's come out. On the other hand, Windows 7 may be a great improvement on vista :/
