I, for one, would love if UIs looked like it's 1995 again. Imagine the crispness, everything is fast, responsive and written in sensible languages. A simpler, and better time.
I don't know you, but from what i recall Windows 95 and 98 were anything but with fast and responsive UIs. Many windows were fixed size, and with significant input lag
I still remember Win 3.1 as being incredibly fast UI wise (once loaded), a feeling that propagated until around the Win7 era. As soon as this newer, non win32 stuff started happening in Windows, I lost that feeling. I have it again on Linux/Wayland, where native GTK controls are just such a joy to use.
And yeah - even if there was lag or slowness I don't recall, imagine those systems on today's hardware. I recently used a WinXP on fast hardware, and by god was that thing responsive, lean and fast.
