Interestingly, our local NBC (prepares to be flogged) station uses Macbook Pros and Safari whenever they want to show a computer (usually just for stuff like, "to find out more, visit nbc.com," etc).
Iron Chef America had a pair of Cinema Displays tonight, they covered up the Apple logo with a X.
Here is a terrific quote about Apple's presence in the movies from the great Roger Ebert (who better to comment on Macs in the movies?):
"Macs turn up in the movies all the time -- not so much because of product placement, but because so many movie people use them and like them. A historian of the future, counting all the on-screen computers between 1983 and today, would likely conclude that Macs represented 90 percent of the computer market.
Alas, this is not so. But since any reasonable person would choose a Mac over a PC, Apple's market share does provide us with an accurate reading of the percentage of reasonable people in our society."
