I don't know why people still use Windows XP ? Its pirated and we all know that pirated copies are not stable. Windows Vista is flop. Nothing but a piece of shit. Windows Vista Home requires minimum 512 MB of RAM while Windows Vista Pro requires minimum 1 GB of RAM.

Linux is the best OS coz you can do anything with it. It have all the daily and office applications. And the best thing is that its free and you have full control over it.
