For as long as I can remember (i.e. at least a decade), I've been the go-to guy for Mac related issues for friends, family and people of that ilk. Recently, I've been telling people to just go to the Genius Bar in the Apple Store downtown. Skip the campus computer store (they're useless), don't call Apple (half the time they make you run in loops); just take it to the Apple Store.
The amazing thing is, most of the time, they come back and tell me good things about their experiences.
