> I can't speak to how consistent or inconsistent these are on Android, because I haven't used an Android device enough to really know.

They are pretty consistent. Swipe to delete in a newer action, but other than that most things tend to have similar functionality. I have mainly used 2.3 and I think I never had issues with finding UI elements. Options button helps when nothing else does.

Back button does have issues at places (browsers mostly) but it eventually takes you where you want to go. I shifted to ICS 4.0 very recently and experience is even better.
