Horses for courses guv.
Just think most of the world not intrested in a new OS, not sure everyones reasons why. But no major effort been made to fine tune Vista and the applications.
So problems which should have been ironed out are still there (mainly with applications and drivers). Catch 22 People hear it has problems with apps and drivers no real major effort to reslove issues and around it goes.
People felt they needed XP to work i guess and stuck with it.
