Apple has noticed that Mac OS X appeals to UN*X-geeks. Coders migrate. But I think the ad is also aimed at Windows users non-the-less, mainly because of the *absence* of Windows in the ad. Indirectly, Windows users are targetted, too. Windows users know that there's this thing called UNIX, or they know there's this thing called Linux, and they know that it's much more stable than what they're using. They also know that it's a hassle to install and maintain (and work on) a Linux system. (It's not true, but 'they know'.) However, they also know that 'Macintosh' stands for the opposite. Macintosh stands for ease-of-use and beauty. Marrying this with UNIX is the best thing Apple can do in an ad. What did the ant in 'A bug's life' say? "We just walk AROUND the leaf."
