Can't speak for 2,3 and 4, as I'm doing OS X dev and it's been some time since I've done iOS. I agree with 1,2 and 6 wholeheartedly.

I'm working with AppKit. I would give a limb to have it be half as nice as the first release of UIKit.

Appkit with XCode 4 is the worst software development toolset I've ever had the pain of working with. I'd rather be using VB or Gtk. :(
