Nothing whatsover......as long as i dont have to actually install it again.

I cant give any expert valuations but i`ve probably given both Windows & Linux a more equal opportunity than most who have ever tried alternative OS`s.
I had only a few months
using Windows(a pc) before discovering Linux last year and although i`ve used Linux exclusively since then i still seem to spend quite a bit of time in other peoples Windows.3 alone this week with an unmountable_boot_volume on one,a ntldr missing or corrupt on another & a winsock problem on the third.
All fixed thankfully but enough to also remind me why i was so darned lucky stumbling across this thing called Ubuntu when i did.
I messed about with Vista for a couple of months and had it on another machine as part of a dualboot...then mutilboot,just to see what might have been.Nothing quite as signature worthy as the machines mentioned of course(1.8Ghz,512Mb).
I just cant see any reasons why i would ever want to use Vista over Ubuntu, although we do have an XP install around.
It`s handy when calling Virgin ts if not much else.
