Yeah, I checked the differences and Pro seems like it is mainly for small businesses and stuff like that, all I need is just an OS that works and is easy to use, I'll let Monkey decide though.
Damnit Hobbit, you use the key Monkey gave you! It was a gift! He was being nice! Use it or I'll travel to England and slap you silly!
On a more serieus note: Pro will work just like any other OS version. It's not going to make you register your own business or make you wear a full suit. It just has a few extra features that you simply won't use, but it's not inherently different from the home edition. Hell, I think I've got a pro version of windows 7, but I'm not entirely sure. There's no reason to go and buy a new OS if you've got a perfectly good one, even if it has a monkey butt printed on it. Hmm, so much for the serious note. Butts, butts, butts.
