Hmm … I'd quite happily do the deed with a desktop PC, they tend to be fairly standard with all the bits they have inside them.
Laptops on the other hand, I've made the mistake of trying to change an OS on them before and came unstuck in painful and embarassing ways … They're just a bit too much Black Box to think about changing the fundamentals of how they work.
This current lappy is picking up the quirks as well sadly, I get the feeling that MS do Weird Things with service packs that don't do much for the continued stability of what they go on …
