...my pc? any help would be great thanks
i heard about some program that allows you to run mac os x kinda like parallels but thats not it. like pearpc?

if ur computer came pre installed with xp then reboot as in back up ur stuff and it will completly wipe out vista hopefully
or buy xp again ??
and u can't get mac os x unless u buy a mac
which is the best choice, buy the new os x Leppard that mac released
