I completely misread '2015' as '2025' and thought these were from this November rather than November 10 years ago. I couldn't believe so many people were still using what appeared to be Aqua-era OS X.
I've never owned an Apple computer, and I still miss the Aqua-era OS X UI.
There was something magical about it.
You might want to check the site again, as the Aqua screenshot is from 2002.
Aqua-era OS X is the best looking out of the box desktop environment in the entire history of computing, and given 1) the lack of interest everyone seems to have in the desktop these days and 2) the directions in which the few remaining contenders are headed, I wouldn’t be surprised if it remained that way for a long time.
It’d be fun, as a side project, to build a pixel perfect replica of it (along with the core apps that make it useful) that runs on a modern Linux kernel and preserve it in amber forever.
