Offhand I can't think of a single thing.
Between 1994 and 2004 we went from Windows 3.x and Classic MacOS, to OS X and WinXP.
Linux went from being a toy to a serious viable OS.
Before: 16-bit OSes with some 32-bit parts, all resolutely single-CPU, many primarily based around cooperative multitasking with no real memory protection, and mainly proprietary networking.
After: pure 32-bit OSes, with proper preemptive multitasking and hardware memory protection, capable of SMP on multiprocessor systems, with TCP/IP based networking.
From 2004-2014 the industry moved from mainly single-CPU 32-bit machines to multi-core 64-bit machines everywhere, with UIs rendered through hardware 3D, and a heavy reliance on Web protocols for almost all network functionality. A much smoother transition but that was because of the big changes in the previous decade.
Linux went from being a nerd tool to a usable mainstream OS that was rapidly taking over the server market. Smartphones went from toys to maintstream. Chromebooks arrived in 2011, and Linux started to become a consumer OS.
Since 2014... er... containers everywhere on servers? Electron apps proliferating? That's about all that springs to mind.
Sadly, that is a low bar to clear.
