If Apple is moving from 16:10 to 16:9, then that would indeed be a very recent development. If this is the case, it would be kind of sad to me (I prefer a bit more vertical space), but understandable given the economics of the panel business.
I don't quite agree with what you're stating I'm stating. (I realize that this has gone on way longer than the original reply warranted, but...)
User teh_klev said that they were sad that 1080p "was becoming" the norm on medium sized panels, and that 1920x1200 wasn't becoming the norm, instead.
I replied that the transition to 1080p had already occurred, some time ago. I don't believe that either teh_klev or I implied that there was mass adoption of 1920x1200 (16:10), only that teh_klev would have preferred that there have been such a mass adoption, and I was suggesting that that preference (which I share, though I didn't mention it[1]) became moot last decade.
[1] though it turns out that if the screen is large enough and the resolution high enough, I no longer care about the precise aspect ratio...
However, for those of us doing "serious" work where we need those extra 120 lines, finding a decent >=21" panel (or even 17" one in a laptop) is getting expensive/more difficult to find.
