I like most of the ads that Apple has done, but some border on the edge of tasteless, with the PC bashing going a bit too far. I agree, though, that the idea here is to generate interest; getting people into stores to look at Macs is where you can make a sale (some people in my classes are talking about getting a mac now that they've had a chance to mess around on my MBP), while giving everything away in a commercial doesn't force people to leave their chairs. That said, 'Better Results' joins my personal favorites list, along with 'Accident' and 'Out of the Box.'
My personal prediction for new MBPs: to be released on Black Friday with the option of a black aluminum case! 😉
