I bought a copy of Corel Linux in 2001 at a USAF base exchange because I was a broke airman and was building my first homebuilt PC and didn’t want to shell out money for Windows, and I didn’t have Internet to pirate it in the dorms (this was the days of no wifi and pay as you go Internet cafes). I thought it’d be JUST like Windows, and I could get shit done, and the differences were just like those between Mac/PC. Just a different interface.
Boy was I wrong. It sucked balls. I didn’t pick up Linux again until Ubuntu in 2006. Now I daily drive Debian. Oh well, at least it came with an inflatable penguin.
Plus it’ll make it easier to quickly restack everything for multiple launches, for stuff like orbital assembly and refueling. We’ll be able to replace the ISS in a week with this thing, once they get a small workhorse fleet going.
