@nprofile1q...After 2k Pro, XP was not a fond experience for me.
I multibooted OS/2 and Linux until I got early access to test Vista, and it was a revelation (once NVIDIA straightened up their drivers for the new WDDM).
I slowly adopted open data formats, then programs, then finally switched to Alpine Linux for myself and my family.
A long road, but as you noted, it need not be terribly difficult (in many cases).
