Good retort. They certainly should push it forward. The continual overhaul is tiresome though... Now they have an entire new language! Not only will I rewrite all my solutions next year, I'll have to rewrite my notes from scratch and learn yet another language.
If all I did was develop iOS/OS X apps I would enjoy the continual improvements, but its tough to keep up with when you also have to keep up with a variety of other technologies (like OpenGL! -- which I have used since Iris GL).
The fact remains, rewrite your iOS apps every year.
Of course this pales compared to the crazy ADHD pace of JS frameworks -- that is truly beyond reason.
I don't get it.
