There are a few entrepreneurial folks out there looking to cash in on your Mac Geekery. Specifically, InsantelyGreatTees has a variety of Mac-centric shirt including, among others, one with a 30 year timeline of Mac history and another humorously called “It Never Happened” with just a big Command-Z.
Of course, if you are feeeling fiesty, FakeSteveJobs is peddling a shirt that says, “Everytime you buy a Dell, a baby seal dies.” Now THAT is poetry.
