Honest answer: Apple is a lifestyle brand, however they manage to offer a superior product to the layman because they have tight control over both hardware and software codevelopment. In my experience, people tend to also like Apple hardware because Apple stores are ubiquitous, so when you need a repair done, you just take it to your local mall and get it fixed rather than mailing it away to Lenovo and hoping for the best.

Out of curiosity, in your engineering course, what are students expected to used to their own computers for? In my experience, any engineering course with labs that would require dongles supply desktop computers anyway. Your school doesn't have desktops in the classroom right? What equipment are you interfacing with that would be easily both mac and pc compatible anyway?
