This amuses me.
And the thing about it allowing future OSes to be cheap or free? Come on, get off it. Despite rumours, Linux and *bsd don't actually require much time to acclimate to. If you have half a functional brain, you can manage to figure out how to do everything you are used to on one of the windows-clone distros (ubuntu, xandros, lindows^H^H^H^Hspire, etc). If you have less, you probably won't notice any difference.
I'm glad apple is patenting it, though. It means that some new distro won't come along and deal that kind of abuse to the poor noobs that don't know any better.
I am tempted, however, to call prior art. After all, Microsoft has stuck adware (some of it unremovable) prepackaged with Windows since at LEAST Windows 95. The whole Windows Messenger thing, as well, was more or less a glorified spam distribution platform, built into the basic services.
