I have to admit, my jaw dropped when I found out I couldn't undo a text edit on my Nexus 7. This was last year; I assumed it had to be something that would make it into 4.3 (no) or 4.4 (still no). iOS's shake-to-undo still feels a bit gimmicky to me (I prefer the keyboard undo button on iPads), but it's something that should have come immediately after clipboard support on Android.
