^ Not having to deal with XP for the most part. Remember, you were complaining about XP and Vista.
So far the only Windows app I miss is Foobar. A nice little music player and tagger. No other player on any OS is even remotely as useful.
What I don't get... is why not have multiple PCs? It's always best to have more then one - especially if you need one to order parts for the computer that broke. (been there, done that a couple times) If they still boot in some form or another I don't through them out, I can always use them for something.
Of course, DH and I have separate computers too... I don't share very well.
