My wife and I went and saw What Women Want yesterday with Mel Gibson, and Helen Hunt.
I saw many Macs, If I remember correctly I saw at least 4 variations during the movie.
1. Mel Gibson uses a PowerBook (you have got to love the big, white Apple on the cover.
2. There is a graphite monitor being used in the main office work area(this is what I spotted first)
3. The CEO or main boss(played a MASH character) had an 15 in. older style LCD display, not like the current version.
4. Mel Gibson's daughter has an iBook in her room, but I only saw it once.
