Apple is offering a free download of a Monk episode "Mr. Monk and Other Detective". Jason Alexander is in this episode and quite funny I might ad. You will need iTunes to get it of course, but that's free, too.
I downloaded it yesterday and I thoroughly enjoyed it while riding my bike, on the stationary trainer, and laughing out loud. I think I could get hooked on this watching what you want to, when you want to thing.
If Apple's goal in givng away this episode is to get buzz. It's obviously working on me.
