right. And the Finder - a piece of Software central to OSX was using Carbon until... when exactly? At most 6 months prior to when CS5 came out.
iTunes - a corner stone of the iPhone software world? Still on Carbon.
If I hate one thing, it's hypocrisy.
Aside of that, nice arguments and well-written. Also, from this perspective, MonoTouch and Unity might be in the clear too as they are not cross-platform toolkits reducing themselves to the least common denominator.
