Not a chance. They need the Mac to develop for those platforms.
Tim is an idiot for pricing these things so high, however - part of the reason I believe we keep seeing these "Mac sales are down" reports (and yes, I know, the current economic climate may have something to do with this... but it's by no means the primary or only cause).
The difference between Steve and Tim is that Steve actually respected the intelligence of the average Mac user (20 years ago the stereotype was college-educated & creative). We didn't always agree with him, but there was a mutual respect. Tim seems to imagine an entirely different demographic (teenagers, "old folks") and along with Ahrendts, tried (and mostly succeeded) in transforming Apple into some sort of boutique brand - higher prices for no particular reason. (Not to mention the older generation today include some of the very people who catalyzed the personal computer revolution in the 60s, 70s and 80s.)
In short, out of touch is the common parlance. 🙄
