Yeah, I edited in that Apple's is "barely better", and that's most of the "barely". I also found the "add" element, though similarly non-buttonish, a little easier to spot, in part because the area in question was smaller, but also because the color stood out a bit better.

The thing about Apple's that's way worse is the photo gallery icon. Pinwheel = photos. So you just have to have memorized the icon to have any hope of figuring that out, especially since there are like 9-10 icons in that part of the screen (plus you can scroll sideways for more).

I also just noticed that, on my view (I assume the icon presence or ordering changes for some people) I have a grey "camera" icon and a grey "App Store" (but seemingly at the top of some kind of "stack"?) icon to the left of the message input field, then directly under the grey App Store icon, on the app list, is a blue "App Store" icon. Naturally, these do completely different things: the blue one opens something to do with the App Store, while the grey one... presents me autocomplete options? WTF?
