I didn't realise how much I missed the iOS 6-esque design style until I saw the old maps UI again.
Sure, a lot of iOS 6 looked dated/heavy, but I think this screenshot is a great example of the attention to detail that is missing from iOS today - just look at the shading and texture in the 'turn event' banners.
I was hoping the flat look of iOS 7 would grow on me... and in some ways it has. However, there is still a long way to go before it feels as complete as iOS 6 did. For starters, something needs to be done about many of the home screen icons. Three years on and they're still awfully inconsistent. Surely there's a midpoint between these two icons.
Anyway, that's my two cents. Just felt like reminiscing.
Edit: To clarify, I'm in no way suggesting we return to iOS 6-esque design. I realise a change was necessary in order to scale apps across different screen sizes. I also prefer a flatter UI. I just think there's a middle ground Apple could have gone with.
For example, the new Apple TV UI is far better than iOS IMO - it adds subtle depth and is more consistent. Same with the OS X Yosemite redesign... they went 'flatter' without losing all personality. Compare the Yosemite 'Contacts' icon to it's iOS counterpart. It's night and day.
