Seeing as how the Powerbooks now come with OS X 10.4, and I received an email for $100 off any mac purchase... I'm getting it within a week or two.
What about gaming, though? I have checked for Mac ports of all the games that i like, and they all exist (except HL2, but oh well).
I know with linux gaming there was no problem playing games with my windows-using friends, but is there any difference with Mac? I'm just not sure if i'm missing something or not, so please put my worries to rest that i'll be able to join in on the same games as windows/linux clients
