It's a sad, sad day in my gloriously all-Macintosh world. Justin Long is the "Mac Guy" in those fabulous Apple ads that leave both PC and Mac guys in stitches (well, at least all Mac guys, plus PC guys with a sense of humor--and they do exist, though not in overwhelming quantities).

However, though Apple is making more of those ads, Justin Long won't be in them. In my world, this is worse news than the Democrats capturing both houses of Congress. But according to a rep, "Justin's a movie star, not a commercial guy." Well la-de-da.

Regardless of any misplaced hubris on Justin Long's part, I mourn his departure. He and John Hodgman (PC Guy) were perfect together. I can't imagine anyone else taking his place. But then...Apple doesn't produce lame commercials. Whatever they come up with, it'll be good.
