Red Hackle,
Unless your daughter needs some special Windows only program, give the iBooks a look. She would be eligible for the student pricing on MS Office 2004 for the Mac, which will allow her to open any Windows created Office document. For music, iTunes is one of the best programs around, on either the PC or Mac.
While Macs don't have as many games available, there is a good selection. Basically only the best PC games make it to the Mac, and then you have many Mac only titles as well. You won't be playing many of the new Windows games anyways on anything but a high end PC laptop, so the amount of games shouldn't really matter.
