Hey all, I've been a part of Mac Nation since December, when I got my white 13" MacBook. I've enjoyed the switch, and I'm not going back any time soon. Part of the reason I love my MacBook so much is the fact that it a) never crashes and b) is very fast and fluid, even during application switching, which is something that my PC could never do well. I've got everything perfect, settings wise. I couldn't be happier. SO HERE IS THE QUESTION: Should I upgrade to Leopard? I've got a 1.83GHz Intel, with 512 MB of 667MHz RAM... I realize the minimum for Leopard is 512 MB. How is Apple with setting system minimums? Will Leopard run, but run wicked slow? Or will it run smoothly...? Like I said, I've dealt with PC's my whole life and am not very sure about how Apple does system requirements. If it won't be running smoothly...where is the best cheap (I'm up at school, money's tight!) place to get RAM for a 13" MacBook? Help is appreciated. Thanks!
