In my experience with both vista and linux (Ubuntu 7.04 to be exact) Vista is WAY more stable. I'm not even exaggerating or w/e, Vista>Linux. The reason you probably don't like Vista is because you don't know how to use it, judging by your spelling...
Again, this is my own opinion/experience. I should also mention that Linux is awesome and the only thing effecting my decision in which is better is driver support (which isn't actually Linux's fault...but...yeah) If I were you I'd dual boot.
*EDIT* after reading my post...I laughed. Hard. LOL I just remembered that with vista a computer professional can do no more/no less that an 80 year old women.
