You may also have feared that you'll get a biased opinion asking a question like that on this website, as you should be skeptical anytime dropping big bucks on a new comp. A suggestion I would make and this would be the ONLY reason not to get a Mac for school is, check out and see what kinda Mac stuff your university offers. I don't mean they have to be Mac based, but it would be nice if perhaps they had price breaks for students on Mac software like office or maybe even they will give mac software for free.(My school has given every version of OSX released so far including Tiger. As well as Norton even though you don't need it. And Office for Mac 2004, X, and 2001.) If you are also wondering about "alternative" downloading sources then say download.com or versiontracker.com there is plenty of FTP sites, Bittorrent, and Acquistion all work great. Also it would be cool if they offered even some minor kind of Tech support, you will almost definitely never need it, as I have not with my Mac(I used them all the time trying to access new networks when I switched dorms from Frosh to Soph year.)but it would be cool if they could like help you set up say like your Mail program. Otherwise I have found my Mac to be completely Plug and Play in *every* ethernet plug I've used, and the wireless capabilities of these things is top notch easy! That is all I can think of. I wish I had entered school with a Mac I could of had a much better time with music, organizing the thousands and thousands of party, tailgating, and other stupid digital photos I have accumulated.
Edit: I did forget to mention one huge problem with Mac laptops. The amount of work you get done may drop significantly when you have programs like iPhoto, Garageband, iMovie and the ease of use and integration with Mail. How on earth can you be expected to write a paper, when you have programs like these at your disposal it's ridiculous, professors however will not fall for this.
Edit2x:Just thought of one more thing, I have heard that with programs like acquisition when downloading music users on Macs are able to get .mp3's that do not have the digital scratch sound that plagues so many .mp3's from programs on PC's like Morpheus, Napster(the old free one), Kazaa, Kazaa Lite. The PC programs have all either been shut down by most universities or only contain the digitally protected .mp3's. Now you must of course delete the .mp3's if you somehow manage to download them with Acquisition, because downloading .mp3's, even if they are high quality 128/bit and don't contain any of the digital scratch sounds that plague PC's are illegal. 😎 😉
