Best thing I did was to get a computer built with #Linux in mind. There's more of them besides Emporer Linux, System76, and Dell now.
So depends on what you use the computer for too. There is proprietary vendor lock-in and SAAS that will only work on Windows or Macs.
Tried Libre Office (Open Office back then) on Windows first and email was online. Easy to switch with just those. Video editing was the only thing stopping me until KDEnlive.
Gaming is different, though.
@cainmark @PurpleJillybeans Steam is getting pretty good (although I only really play older stuff)
