I don't particularly like iTunes, but it does two jobs for Apple: it syncs iPods and makes Windows look bad.
Granted, it's not third-party since Apple owns the Carbon layer and iTunes, but then again, Flash isn't third-party for Adobe's in-house developers for the very same reason. Perhaps this is what Jobs means by "painful experience".
What I don’t understand is why Apple haven’t done a standalone version of their Macbook trackpads. I’d buy one of those for sure.
Not sure how those work if you're not using a Mac. Maybe you can remap the right Option to Control? Control isn't near as important for most Mac users since Macs use Command where windows uses Control.
That said, once I did the ctrl/caps remapping I've used that keyboard extensively with emacs and only occasionally did I feel any real limitations.
OSX is great software, the iPhone is a great product, the original Macintosh changed computing forever. That, IMHO, is not "just better marketing".
