My household still has iOS 6 on 3 out of 4 iOS devices.
I hate iOS 7's design just as much as I did last June, and it was enough for me to put Apple off my radar. Thankfully, I was on Android full time since 2012.
Ever since playing around with a very old Mac many, many years ago, I was amazed by Apple's UI design. It just felt so refined, so understatedly classy, so much nicer than the technically beefier Wintel stuff. Year after year, Apple never failed to deliver on the UI front, even OS X 10.0 was surprisingly refined for a "revolution" product. Until June 10th, 2013.
I don't want to hear any rah-rah about modern/functional "flat" design. I still yet to hear any good arguments for it. I still don't understand how Helvetica Neue Light is a great choice as a system font. I still don't understand how 90s clipart is nicer than photorealistic icons. I still don't understand how a very badly implemented Web-style design defers to content. I still don't understand how these crazy neon colours are nice. I'm still not digging that yummy yellow on white.
Yes, flat UI design is a trend, but Windows Phone and Android have at least made an attempt to implement it well, and I never expected any remarkable UI work from Microsoft and Google. Apple has just ripped off UI assets from these systems, put that on top of the iOS' UI structure, slapped some cheesy FX on top of it and bounced some buzzwords about simplicity, clarity, no ornamentation, etc.
The exact same arguments have been used in defense of 60s-70s "functional" architecture. I don't want to fall prey to this nonsense. I don't want to overpay for hardware to get a UI that is a derivative of more bang-for-the-buck stuff. I don't want to convince myself that fast food UI design is modern and haute UI design is dated, "boxy", "clunky", "dark" and skeuomorphic.
I hate iOS 7.
