This is one of those form and function debates. I use a PC and have used Mac's. They are really very different animals. Mac's do graphics very well and are "friendly" to people who are computer shy. I use PC's because Mac's will not run my software nor do I see it happening anytime soon. I use engineering/math based software that will not interface with a Mac. There are some programs that are coming out as Dual Platform which is nice but doesn't address my issues. If all I did was look at pretty pictures and word process then I might like Apple computers. Until Apple steps up to the plate with decent program capabilities for science applications they are going to stay on the store shelf for me. (Linux is great and runs on a PC so you don't have to run a Windows platform.)
