Last point first - as a student you would get educational discount on hardware, some software, and AppleCare.
I have experience of a range of desktops and laptops. No manufacturer is perfect. However, my Apple problems have been resolved more quickly, and with a lot less trouble than the windows machines I've used. For example, when my son's Apple ibook motherboard failed the staff in the Apple shop confirmed the problem, then removed the hard drive and put it into another, new, ibook. Job done in about 15 minutes. With my Toshiba laptop a comm.s board problem took two weeks to fix - and that was with the benefit of an extended warranty.
This stuff is a little old now - but I believe it still holds true:

While in New York, I paid a visit to a glamorous downtown computer shop in the hope of being tempted. Although I have a laptop that works perfectly well, I wanted an excuse to buy a new one, especially as computers are much cheaper in America than they are in Britain.
With my friend, Mike, a patriotic believer in the American way of commerce, I approached one of those knowledgeable and personable young salesmen that Macintosh employs to encourage customers to part with their money.
"What kind of computer do you have?" asked the salesman. "A PowerBook G4," I replied. "A PowerBook G4?" exclaimed Mike, striking his forehead with his hand in mock horror; for he knew that I wanted to be persuaded to replace it. "That's a good machine," said the salesman. "How old is it?" "About five years," I said. "Five years old!" shrieked Mike. But the salesman said: "I'd hang on to it if I were you. It should be good for a while yet."
"Who on earth trained you to be a salesman?" asked an astonished Mike before we left the shop empty-handed; the young man just smiled. I am beginning to be worried about the future of the United States.

When you pay the apparently higher price up-front for an Apple it should be considered an investment - less time wrestling with Windows problems or suspect hardware later.

While nothing is perfect, Apple users tend to be happier about their computers.
