I'm extremely unimpressed with the software engineering coming out of Apple recently. So many of their major new iOS APIs either don't work (Core Data/Sync), are just not well thought through (Storyboards) or seemed to have been designed with much real world testing at all (AutoLayout).

They have a great foundation in Obj-C/Cocoa Touch but I'm very quickly losing confidence in their ability to move the platform forward.

Android is much less mature in many ways but seems to be under much more expert guidance lately, both architecturally and at the UI level.
