I know that feel. My story is pretty much the same.

The most frustrating part is that Apple fanboys now justify their love for iOS 7 using the exact same arguments they used to dismiss Windows Phone.

I didn't buy the "Go easy! It's still only beta!" stuff. The changes that happen in beta are along the lines of "Apps no longer crash while activating the radio while audio is playing." not "Complete icon redesign".

However, some of these (Z-Index? What?) should've absolutely been fixed before GM.

But months ago these were quirks in a beta release. iOS7 is now released software, and it's expected to have matured.

The problem is that it looked like a very poor design decision rather than a beta version quirk even back then...

the sooner you stop caring about the up/downvotes of strangers on the Internet, the happier you will be.
