My previous PB G4 developed a problem with reporting last-use dates for files; no matter which file you picked, it would report its last-use (or last-modified or last-accessed or whatever you want to call it) date as 5/1/06. Every single file. Even iTunes reported every track's last-played date as 5/1/06. I've recently upgraded to a MacBook Pro, and I'm getting exactly the same problem. I can't believe that it's just spontaneously doing it and coming up with exactly the same date for everything (still 5/1/06), so I can only assume that when I used Migration Assistant to transfer the files over from my PB G4, it also transferred whatever it is that's screwing up the "last use" date. FWIW, iCal and the Dashboard calendar always report the correct date, so it must be a "hidden" setting somewere else. Can anyone suggest anything that might fix this? It's more annoying than you might think.
