XP Pro to 7 is a good move. 8)
Get in before 8 comes out!
I'm continually amazed at what it copes with, they've really sorted out an awful lot of compatibility issues!
Though having played with W8 they've improved an awful lot "under the hood" but the UI is just plain INTOLERABLE.
I do have to admit to buying
:
1. a W7 license pre-release at a "bargain" price.
2. A W7 triple-pack, again at a ridiculously low price, 1 used, 1 "given" to a friend and 1 unused.
