I never 'liked' XP. Always more clunky than either 98 or 2000. Just as stable as 2000, but more sluggish on hardware available until around 2004. I didn't upgrade until my hardware choices basically de-supported 2000/98. I never liked the activation scheme they introduced (Windows Vista's and 7's activation scheme of any disk, 1 key, makes much more sense than loosing the media, but still having a now worthless COA). Driver installation was a pain. So were SPs. Loved the 'partially supported' XP SP3 thing, with incompatibility for AMD chips, even from Microsoft Updates, that auto-downloaded it... The only thing worse than XP was that Vista was such a resource HOG that it make XP seem downright spiffy, despite Vista being much easier to install, with better auto driver support, even though Vista also lacked a lot of legacy support...
I am so happy with 7. I can't wait for XP to die. I love that even old old systems and underpowered netbooks work better with W7 than they EVER did with XP... Even with a gig of RAM and a 60GB HDD...
I celebrate XP independence day... Do you?
