Some people hate change, I remember when XP came out and how unpopular it was with the 9x lovers. Then Vista was terrible and XP was great, etc etc. However change is innevitable, so if there is a backlash it will be a minority and in a couple of years nobody will care anyway as there will be a new version to hate.
There is truth to this, but XP is something of an extraordinary item by these standards - Windows 95 didn't remain on sale for eight years after release, wasn't still getting active support/updates
eleven years later, and didn't remain in major use until present day (estimates I've seen put XP at somewhere around or just below 7 for market share.)
95 was a step in the right direction, but it never got to become a really mature, stable OS; XP has, and consequently it's got a
lot of users that aren't going to give it up until they absolutely have to. Tons of businesses still use fleets of XP workstations, many of which are definitely not 7/Vista machines, which means XP isn't even going to come close to going away until they're ready to do mass upgrades. (And in
this economy? Good luck with that.)
