Kutztown University (near Allentown, PA) is very Mac friendly, to the point where it actually has more Macs than PCs. This summer, almost every computer on campus is being replaced, and will be running OS 10.3 and XP. A new wireless network is being installed, as well as residential and acedemic buildings getting seperate (but linkable, in an emergency) networks, to minimize downtime due to windows viruses. The bookstore is an Apple authorized reseller.
While there is not a leasing program for laptops, it is possible to sign out iBooks and Powerbooks from the AV center (PC notebooks must stay within library).
The school is a mid-sized state college. It has a large art program (including Communication Design, among others). There is a very good film/broadcasting department as well (the reason that our library has about 100 Macs in it 🙂) I was a history major for 2 semesters before switching to biology, and I can attest that they have several very good professors within the department (one of whom was an advisor for the movie "Gods and Generals").
