As Saab says be careful with the drivers. My In-laws have an HP laptop with Vista on it. MIL hates it and wants XP. Trouble is the Hard disc is Sata and their version of XP can't see it without drivers. Guess what Hp don't do XP Sata drivers for their laptop and it's 18 months old so probably never will. Stuck with Vista for them then. Don't see the problem myself, use Vista Ultimate all the time on my Dell laptop, no problems at all (except for getting DNS settings in TCP/ip at times, Vista cocks it up so bad that I am on user settings

, not a problem for me

but if you don't know what it is then you are on a hiding to nothing).
