Everything (or 90%) on the iphone was taken from the mac and put into the iPhone. The software dvelopment for the PC environment, then stripped down and streamlined for the phone is why the iPhone was the revolution that it was.

Apple, like you, can only think in terms of revenue and profit generated. "iPhone makes this much profit = iphone gets this much development".

That thinking has led us into this stagnated crap, because it's a terrible way to do software. Worse, what's happening now is apple is taking its iThing software and trying to migrate it to the mac. The Mac is now getting destroyed by the iPhone development.

That is the reason why.
