Desktop usage (terminals, browsers, editors, word processing, spreadsheets, presentations, media listening/viewing and light creation) should not be surprising. It should not change out from underneath the user.
I've run Debian Stable for more than 15 years as my primary desktop system, almost always with XFCE. I add the Google Chrome repository and download the latest Firefox and Firefox Nightly. That's it. The whole thing runs really nicely on an i5-2500 with 16GB RAM and 2 SSDs in a ZFS mirror. I'll need new hardware when I switch from 2 1920x1200 monitors to a big 4K screen; I won't need to change my OS.
