i'm on a pc and macs seem very appealing to me. i would get one if it weren't for two things:

1) from what i understand, macs are not very easily upgradeable. i am a college student and i stayed under my budget by building my own computer...used some parts from my old one. you can't do this with a mac, correct?

2) i have all of my software for windows. its a big jump. but i understand there is an emulator in which you can run windows based programs on a mac? i haven't done much research so can someone confirm this?

the jump seems too hard...
