The software support will probably be around for awhile yet, but it's a question of whether you'll still be happy with the performance in a couple of years. The MacBook Pro has a much longer useful lifespan ahead of it.
This is especially true since you're a newcomer to Macs. You don't have any legacy software, and even if you have to run MS Office in Rosetta (a real-time PPC-to-Intel code translator) it will still be just fine until there's a native version of Office.
Speaking of which, do you know what apps you'll be running? Some comp-sci and engineering classes may need Windows-specific programs, but if you're mainly writing notes, spreadsheets or doing presentations, the MacBook will be fine. You'll probably want a copy of MS Office 2004 (Student & Teacher Edition is $149) in the latter case.
