I'm on the same boat. The specularity around edges don't match the refraction patterns and it throws me off every time. Somehow they thought this wouldn't affect readability of whatever button or panel it's applied to. They also use the specular bits as a border that's also so uneven depending on which direction light hits from. I noticed that some of the dark panels had almost no borders at the lower right corner.

Another bit I'd like to pick on is the speed at which transparent context bubbles spring out. Waiting for a panel to bounce back and forth so that you know where to put your finger next is so bad as a UX choice that I'm losing confidence in Apple.

From a visual point of view, there is now flat design mixed with this voluminous transparent design which is a weird combination of skeuomorphic and abstract designs in one. I really don't know what they were thinking.
