It is definitely much better executed than iOS 7/8, but still uninspired and unexciting, just "good enough" and current.
That's your opinion.
Unfashionable ≠ outdated.
The UI design changed very little from iPhone OS on the original iPhone in 2007 until iOS 7 in 2013. To say that iOS wasn't becoming outdated after looking relatively the same for 6 years is a bit naive. Especially considering the rate at which the technology and design of the devices themselves advanced in the same timeframe.
Many flat designs are arguably even more skeuomorphic than classic iOS. They are often trying to imitate print typography on some kind of advanced e-ink instead of morphing a touchscreen device into a specialised device.
The faux leather and green felt were the worst part of the classic iOS design. Aside of them (and some other textures and glossy effects), that UI had tons of sublime detail, perfect chrome/controls/content/eye-candy balance and understated beauty and user-friendliness.
I'm not sure what your point is here.. I'm saying I liked the design of iOS 6, even what you call "the worst parts." And besides, I think when most people think of Apple and skeuomorphic design, they think more of iOS 6 and the design of many apps that were inspired by and created to look like certain real life objects.
Yes iOS 7/8 is very skeuomorphic, but in a much less obvious way, with much less ornamentation.
You could get flat design (which is arguably better than most attempts at ornate UI) on Windows Phone since 2010 or on Android since 2012 (not counting Honeycomb). iOS 7 felt to me (and still feels) like a bad derivative of Android's take on flat UI with some added pastel and neon and early-2000s-Flash-style FX. Absolutely nothing exciting.
I could have accepted this change if the new UI at least had functional advantage. As of 8.1.3, I don't see any new features that couldn't have been done better with the classic iOS design.
What did users gain from the trendy design? Shouldn't the resources have been spent on refining iCloud, Maps, iWork '13 and big new features (like fingerprint scanning and not like third-party keyboards) instead?
Well, I for one think that the UI is much cleaner now, there is a lot less distraction. Looking back at iOS 6, I see a lot of unnecessary embellishments, which also provided no functional advantage. That's my opinion.
But the way I see it, the redesign that came with iOS 7 was less about function and more about updating the look and feel of the software to match the quality level of the hardware. Like I said before, with each iteration of iPhone and iPad, the design and functionality had always improved, but the UI was the same for a long time. You have to realize that the world is becoming increasingly more fast-paced, especially where technology is concerned. In that type of environment, things tend to become outdated even more quickly than they used to. With iOS 7, Apple wasn't just changing the design for the sake of change, but it was a big thrust forward into the future for Apple devices.
Whether people feel that the design is derivative isn't really the point, the point is that Apple felt it was the right change to keep their flagship devices current and updated. And they weren't wrong, the new design hasn't hindered their sales, in fact it's been quite the opposite.
Also, the people working on iCloud, Maps, and iWork are most likely not the same team as the people working on the overall UI design for iOS.
iOS 8.1.3 is definitely much more refined and bearable than iOS 7.0.0.
Agreed.
