Another level of simplicity is licenses and DRM. I've got multiple computers and OSes (Win, Mac, Linux). I'll have more computers in the future. The words BSD, GPL, and public domain simplify my life enormously. There's a tradeoff when I have to pick which open source implementation is best, but I would much rather do that than read legalese. And unlike proprietary software, I do not pay rents based on operating systems or have to think about how many computers I've installed something on. Ignorance is bliss.
