I do not know if they will last longer physically, but usage wise they do I think. The Mac OS is not as resource hungry as Windows. My wife had a laptop that would still be working if she had not offered it a glass of ice tea on the keyboard

Oh well, these things happen. And, another good thing is that you can now easily run Windows on an Intel Mac. There is a program built into the newest OSX release and there are two other programs for other vendors that let you run Windows. I run the program named "Parallels" and Windows XP on the Mac I am using now. My wife must use Windows to log in and do remote access for her job sometimes. Only my laptop has this program. To show how easy it was, she got up sick one morning, called into work to tell them she wasn't coming in, then grabbed my laptop and signed into her work account to sign off payroll that had to be done that morning. The easy part was that she figured out how to do this without ANY prior instruction from me, and she is not a computer wiz [I am not either but I know more than she does.] Also, Windows run well on my laptop and my laptop is only a MacBook, not the top of the line MacBook Pro. I hope this answers your question. Sorry if I rambled, but as they say; "Once you go Mac you never go back".
