I feel so old now…
I kind of get the appeal, but it's also unnecessarily skeumorphic/fake-3d and there were some UX things that made little sense especially lumping all the window controls all together (including the destructive "close" X) where MacOS smartly separated them.
Interesting that modern macOS now have them next to each other, like Windows.
You'd be hard pressed to call the Window 95 UI pretty, but it is really functional. I'm still a firm believe that the majority of the work we do with computers today could be done within the Windows 95 shell. We need 64bit, more memory, faster CPUs, GPUs all that, but the modern UI aren't really "better", if anything many of them are more confusing. I think a lot of office works would be happy to just have kept the Window 95 era UI for Windows and Office.
It’s like there’s always just a little extra brain power and attention being used by modern flat UIs, and you get to shut that off when you look at a depth-enhanced UI.
Windows, for instance, has dozens of ways to do that, and you can find parts of Windows that use an archeological version of the controls. Nobody, it seems, bothered to reimplement the older APIs on top of the new ones.
EDIT: Sun's OpenLook is the other one from that era that was fantastic
Windows3 and Motif hid this stuff under a menu, so wasn't a huge concern.
But then Windows95, and then (oddly) MacOS through this away in favour of throwing them all together.
Awareness of spatial patterns / frequency of use seems to have been higher among early UX/UI designers than after. I guess maybe because mice became more accurate?
