My colleague update his Mac a while back and I commented on the wild difference in corners between finder and word from across the room. I had to walk round and physically point at them for him to know what I was on about, and then he says "oh yeah, guess they are a bit different"

To my designers eye it was the first thing I saw, to him it was nothing.

I still think it's bad and a sign of a change in apple focus/style, but it's clearly not an issue at all for a lot of people.

Said colleague did get cross when he struggled to resize a window though. Turns out inconsistent corners means inconsistent handles. And that is a real problem.
