Most campuses have a "Work-At-Home" licensing agreement with Microsoft, where employees of the campus get huge discounts (Vista Ultimate for $20, Office Mac 2008 for the same price) so they can install Microsoft apps on their personal computers and "work at home". Student employees also share this benefit, but Microsoft also has student licensing (usually available at your bookstore) that lets you get Office for ~$100. Check with your campus IT about the "Work-at-Home" licensing. My campus uses this reseller to handle its Work-at-Home licensing. Good Luck
