The University of Wisconsin - Stout (Menomonie, WI - an hour east of Mpls/St. Paul, MN) has three majors or so for which all incoming students are required to have PowerBooks (leased at $500/semester). Majors with this requirement are Graphic Communications Management (GCM), Art & Design, and Technical Communications. All other majors receive Compaq laptops at $500/semester. The campus is wireless-equipped, with a good signal available almost anywhere. The GCM labs are also equipped with G5s and high-end G4s. The bookstore on campus is an Apple Authorized Reseller, however, that may not last much longer, since all incoming students are required to have laptops anyway.
The laptops are leased from the school, and may not be modified physically. After two years, the students are given new laptops. An option for students to purchase the laptops after two years was discussed but determined to be cost-prohibitive.
