Clearly, Apple is not improving on its desktop products as much as its mobile ones. Apple does this because it sees iOS devices as the future and rather than dumping its resources into the waste bin of the past (cough cough Windows and OS X) it puts its resources into the garden of the future. (iOS devices) In the future, expect more of the same. Expect Apple to vigorously iterate on its mobile software, and expect OS X and Windows software to suffer as a result of growing neglect. It may seem like a bad idea for Apple to do something like this, but when mobile devices overtake PCs, Apple’s iteration on mobile software will have paid off.
