Def get a Mac, I'm using the same MacBookPro I bought in (( spring of 2006 )) it's been all over the world with me several times, it's never given me any real issues, once I had to take it in, it was fixed in minutes and didnt even cost me. It really only needs some more memory bc it's slow at times, for instance on TW when a thread has a lot of GIFS etc.
As many sites as this Macs been to, there's no telling how many PCs I'd have gone thru over an 8yr period. My experince with PCs, has been they're garbage. The ones I've had I wanted to crush with a sledge hammer then pee pee on'em.
