PC -> well that is fairly obvious.
BSD -> The one and only, based on the original BSD/Unix NetOS just fo you
( the above just says it ALL )
I think "PCBSD", or is it "PC-BSD" ?, whatever, its only 5 letters and quick to remember, is just fine.
...if you haven't heard of "BSD/Unix" then you probably aren't reading this anyway -LOL.
Consider the existing alternatives, like ... GhostBSD(not much "tangible" there), or Dragonfly (wow, they named it after a "BUG" !), or Midnight (...yawn....)... wtf? those names seemed dug up from somewhere in between StarWars and LoTR ?
I miss "Beastie" the most, and I wish PC?BSD would include different cool wallpapers of "Beastie" -that is the least they could do in appreciation of the great FreeBSD.
To me, the ix-OS with the coolest name and logo is OpenBSD ('da Puffer). "Open" really does say it ALL
