Let me put it in a different way.
When Everybody was bored using XP for almost 6-7years, MS did try to trick people along with hardware manufacturer's and released a hardware hungry OS called Vista.
being blessed by God (read as Economic recession) very few dared to go with Vista, upgrading the hardware, but ekk...it was a waste..total waste.
Now in 2009, after approx. 2 years people kicked vista and posted it's limitations/downsides/downfalls/etc....MS combined all of that into Vista and rather than coming up with Vista SP-2, they came up with Windows-7.
This time the recession was wading away (very slowly) so W7 was taken by many in good sense (apart from a few like me, & others after checking a couple of posts here

)
Now for those who got it as free through p1r@ted, or giveaway or whatever other than buying----njoying using it or get back to XP...
for those who purchased it, i think it could be returned and so get ur money back.
Disclaimer: No offense to anybody
