In addition to the points that you made, there's the issue of source control as well. XIBs have always been a pain with source control, but if one insisted it was workable. I just haven't seen a way to make storyboards work with more than dev and not end up with someone going bald from pulling their hair out.

There's also the issue of requiring iOS 5 to use storyboards.

Just going to quote myself from a previous post:

There's definitely room for bias in the stats I've seen but virtually everyone reports almost no iOS 4 devices.
