I didn't use the Aero effects much but they sure beat this flat look.
I have the same issue with Mac OS 10.10 Yosemite. What the hell got into the designers? I was disappointed by Microsoft's but I was shocked that Apple did it too. WTF.
It's gotta be something to do with having limited CPU/GPU horsepower in the handheld devices, and not wanting to waste battery life on shadows.
You have this right. Microsoft went to the flat look GUI on Windows 8 because it uses less system resources than the Aero look you get on Windows 7. Now you have enough juice on a desktop or laptop to run Aero with nearly zero problems. But on the smaller devices you mention it is a problem.
So for the sake of a uniform GUI experience across the board (meaning mobile devices/laptops/desktops) Microsoft went for the flat look in Windows 8. Which is also why the start button and old desktop was gotten rid of but that was unnecessary and went too far. A very stupid and stubborn decision. 8.1 still does not have a legitimate start button......
So I install Start8. How much IQ does that take????
