First Microsoft with Windows 8 - flattened UI elements, soft unshaded coloring, squared corners, etc. I dub it the "crayon look" - both because of the dumbed down simple look, and because of MS seemed intent to treat us like kids using crayons, instead of intelligent users who prefer a more polished look. It took years to finally get the sculpted, more-pleasing look of Windows 95 (remember Windows 3.1?..it was 'flat'). Now we're being regressed backwards.
After Windows 8, many apps and websites began updating their own visual schemes to "the crayon look".
Then Apple follows suit (essentially) with a similar style in OS X Yosemite - and iOS8.
Now we're going to have the same thing in Android.
It's like they've all become lemmings, rushing to trample off the edge of the usability cliff!
I kept hoping this was a temporary trend and I could wait out these releases until sanity returned...but it's starting to feel like they've all drunk the same kool-aid and this isn't going away for a while. How long before most major Linux distros start adopting the 'flat' (crayon) look, too?
