what was the reason you got it for? did you get the new model with the new track pad? set up your email and start making rules for the junk, that should take some time.go to versiontracker.com and get some free/share ware and do something with it. if you really want to, load a copy of XP SP2 on there with bootcamp and start fighting all the internet crap that affects windows. enjoy
There is only really one B&W difference. The chance of virus/malware getting on your machine is a little bit less, Though the support is harder to find, other than directly from Apple. Other than that, most programs run equally proficient on both PC and MAC platforms. Thats about as straight forward an answer you're going to get seeing how I equally like both. Not a fanboy. I think Mac's by nature are far sleeker and innovative, though PC provides an equal product as far as functionality goes, and they do it at a lesser price.
