A little bit of nostalgia mixed with “good riddance” comes to mind - kind of like when compiz screen effects were all the rage. (Exception on that front: I still love wobbly windows to this day.) Noisy desktops were fun for a while, but got old. I particularly recall reading about ubuntu coming under fire for the drums it used to play when the greeter was ready for login, because it would disturb college classes.
The TV show “Babylon 5” offered a “Shadow Wars entertainment utility” CD-ROM for win95 - still available today for dirt cheap today at amazon - which includes what today might be called an “audio theme” that automatically tied win95 events to audio snippets from the show: “Aw, Nuts!”, “You are executing an illegal order!”, “I have to deny your request”, “Are you sure you wish to go through with this?”, etc. That awful OS would generate so many errors & prompts that after hearing the clips umpteen gazillion times (before switching to Redhat in 1997), many are burned into my brain & I can replay them in my head just by reading the 8 character filename. Of course I sucked all those wav files off the disc & have them at the ready should I ever need them, or feel the need to reminisce. I know my kde plasma desktop offers a slew of events that could have an audio file tied; I’ve never looked into how many such events gnome offers.
