It’s as all the arguments have said, XP is "good enough" and most individuals and businesses alike see no compelling reason to upgrade. There are reasons to upgrade, just not enough reasons to justify the cost in most cases.
Granted, if you need a new computer(s) then most likely you will be getting Windows Vista with them.
And I suppose that’s the only reason where the upgrade is justified. Vista does offer better security, the jury is still out on whether it’s slightly slower or just as fast as XP under different circumstances but many complain that it’s hard to use. Personally, I’ve found it easier to use than XP and those that speak of learning curves are probably not that computer savvy.
Gamers say XP is faster, most "tech heads" recommend sticking with XP but come the end of this year, no one will be able to get a new copy of XP to save their life.
It’s bye-bye to XP at the end of the year as Microsoft will end distribution of OEM copies in June and cut off supplies to manufacturer at the end of December. The company is going to force us all to adopt Vista whether we like it or not. Expect similar behavior when Windows 7 releases but maybe we will actually want Windows 7.
Before I hear from the Linux crowd, yes, it might be an option, if only the hardware support wasn’t so poor. And no, I don’t want to use ndiswrapper or visit the command line, thank you.
