If you're not familiar with the Mac OS, then I would start by finding a library, or other publicly accessible Mac to play with first. You may well find (as I did) that you just plain don't like it. I had one for a short time, and found that there were certain things (Lack or a right-click context menu etc) that I just disliked so much I wouldn't want one. On the plus side, if you like 'em, you like 'em, and compared to almost all other computers, they're VERY well made. As far as what you need goes, your best bet will be to go into a knowledgable computer store (NOT a big-box store) and discuss your needs with them. Good luck.
