And the loss of skeuoumorphism. As much as designers chide it, skeuoumorphic interfaces are, when done well, a massive improvement in usability compared to flat/monochrome ones, both for new and experienced users.
It's not really visual "clutter", the shadows / pseudo-3d elements help the brain distinguish between different types of elements, providing contextual information.
Yesyesyes this here. Icons need colors, the smaller the more. Otherwise, they might as well be gray blobs. Peripheral vision works with colors, but it doesn’t do finer details.
rant:
But in the end, user interfaces are mostly “dead” anyway. No more structure, no more colors, no more icons. Everything is a flat sea of labels and boxes (or sometimes even just lines) floating(!) around. And no two user interfaces use the same style, even from the same vendor.

Isn't the Apple Menu basically a start menu though?
Written words don't have colour, and you can parse those with ease.
Unless you don't know the language well, then icons are very helpful.
Yesterday I booted my 350MHz Power Mac G4 for the first time in 13 years. I booted into Mac OS 9.2.2. I remember the Apple menu having icons for every item. Once again, though, every icon was in color.
