Granted, the pirated version of Windows 7 has no features, therefore it is worse than Vista (which still has features).
I wish that people would stop complaining about Vista and start complaining about XP. :D
It depends on how much RAM you have, but Windows 7 runs OK (not as good as XP did) on my Pentium 4 PC, but it does have 768MB RAM and integrated graphics (which got 1.0 :P).
