Vista is a very little (for age) system and it's not working correct sometimes. I will put Vista on my comp but maybe after 1 year when all "bugs" will goes from it away. Stay with XP Sp2 and all will work fine.
BTW Vista is only was created for wireless tech. like bluetooth or GPS ....etc. I don't think that it's good for some work with music. Anyway all recording studios in Kiev (that I know) that was instaled Vista now back to the XP.
So my opinion is XP
