YES THEY DO, If YOU are a developer I suggest you watch the video on UI design elements of 7.0, as I posted elsewhere due to NDA I cannot provide you the image, but I gave a response in a similar thread About the UI design and thought process.
Just because the elements within the icon backdrop (glyphs/symbols) adhere to a grid, does not mean the icon is designed properly.
You have to take into account, colour tones, highlights, drop shadows, light sources.
ALL of these elements have to co-mingle to make a great icon/photo/design.
The icons and GUI elements, as they stand now, do not follow any coherent guideline, and are definitely not attractive visually.
But, what do I know.

Oh stop with the Steve must be xxxxxxx or it wouldn't happen under Steve... It's bollocks. Many things that shocked people were done under Steve.
OS X for one. People bitched and whined about it calling it's UI juvenile against OS 8 and OS 9's. They adapted. The same fricking thing will happen here.
Steve however had a sense of design, and knew what worked.
The morons who came up with this new GUI obviously do not.

Not necessarily, a common person knows nothing about UI, that is how iOS came to just be accepted, it was the first mobile OS for it's kind, and the UI was standard, I am pretty sure had iOS began like how 7.0 looks today and then 7.0 released with iOS 6 UI, people would be outraged over icons and textures etc. No one is doing it wrong, people just aren't appreciative of the work Apple has put in, there are MANY great API's available, and the UI is also elegant, and less clunky. Content is shown and not so obscure. We Developers are looking forward to this release, and I am sure consumers will be just as excited.
The common person doesn't need to know about UI, because a good UI will mimic real world scenarios, such as buttons to be pushed.
Consumers don't care about API's!
They just want it to work, and look good while doing so, in most every case!
Some developers remind me of hardcore gamers who don't give a **** about aesthetics, but only what the internals of their rig can do!
