From my good friend, Brent:

"[T]he only people who bring up the supposed value of IBM/Windows over Mac are people whose livelihoods depend on it. Those PC vs. Mac commercials are correct, and Jerry Seinfeld can't fix it." (It's worth noting Brent's livelihood does not, in fact, depend on the Mac. He's just a satisfied user of one at home, whereas his work computer is Windows-based.)
