I have long hated Macs - but I'm actually switcing - my current laptop is dying so I'm going all gay and getting one of the new Alum books. If I don't like it, I can just put Linux on it.
I think in terms of Apple, the iTunes stuff is the best money making idea that they have had yet. Everything about it is a good idea to me. They should be able to make good money off of that - very low overhead on that.
Now that they aren't limited with their one killer app to their own platform, they are essentially going to kick ass.
They are marketing via Pepsi, which I hate - but giving away 100 million songs. That is huge.
