"a Mac is like a car that gets 500 miles to a gallon of petrol... but you can only drive it on designated highways."
I don't own a Mac but think it to be a superior operating system (every newspaper I know of uses Macs in their offices-- better graphics etc.)The only thing to watch out for today is the price/product factor. You can search the following if you like:

Leo is an advocate of Mac but he's mad at them right now. Seems he bought their new product 6 months ago and now a newer product does more for less money. ie bought an E300 and the now the S Class is the same price. His "lesson" could be of value to you when you make your new purchase.
I haven't fully searched the sites for Mac info but if I find anything useful, I'll report back.
