BluSponge knows what he's talking about
I've used all three major OS platforms (Wintel, Mac, and Un*x). I use a Mac for my personal use, Un*x for "at home programming", and Wintel (NT/2000) so I can pay the bills. Among the three, I've found the Mac to have the best (designed and attractive) interface, second highest reliability, and highest "ease of use". The Un*x variants have the highest reliability, but take a fair amount of effort to setup, and unless you're a programmer the interface probably leaves a lot to desire. The Wintel boxes (especially the monstrosities of Win 95/98/ME) fail in all three areas - invariably, I've found them to run a poor second to the Mac in interface, a distant third in reliability (even the stable NT version must be cold-booted approx every 10 days), and "ease of use" doesn't even enter the chart.
The *ONLY* area Wintel boxes win is their omnipresence; everybody uses them, so at least you'll have a safe topic to complain about over a water cooler.
If you're a business major, you don't need to worry about your major software - Word, Excel, and Powerpoint all work on the Mac. (Of course, why you'd want to use them besides the "work environment" issue is another thing.) IE, Netscape, Mozilla, and Opera all work on the Mac. (I'm typing this in Opera, on a Powerbook G3, as far as that goes.)
Games are a problem, yeah, but you're better off buying an X-Box anyway, for a fraction of the cost (and a multiple of the game capability and reliability) of a PC.
As far as cost goes - yes you can get cheaper in the PC world. You also get what you pay for. Macs tend to use higher quality (and more technically advanced) components. A similarily equipped PC (using the same quality components) built from the ground up will probably cost the same (or a little more). Mac notebooks also tend to be a little lighter than your run-of-the-mill PC notebook. The lightest PC notebooks (like the Vaio) are lighter, and usually cost more.
That's all evangelist talk, of course, and while I could continue in the same vein, I'd suggest you go to your local CompUsa and play around (as extensively as they'll let you) with the various notebooks. You might also want to check out the following links :

I'll assume you can find the equivalent PC sites on your own.
