Apple is running a new multi-banner Web ad campaign in which the top banner states, “‘Leopard is better and faster than Vista’ -Wall Street Journal” and the familiar Mac (Justin Long) and PC (John Hodgman, who’s a Mac user himself in real life) characters begin in a large vertical ad on the right side of the page.

Mac stays in that banner, but PC actually moves from one to the other via step ladder as he “fixes” the Wall Street Journal’s by stapling a “NOT” sign at the end.

After he finishes his task, PC says, “Come on Mac, we’ve got the whole Internet to correct. Grab the ladder.”

Here’s the ad as seen on The New York Times Web site:
