Thankfully, there are several alternative free unix-like operating systems these days. Are they are popular as Linux? Do they have as much big business/corp backing as Linux? No and No. However, if Linux implodes there are great alternatives these days. I personally use and quite enjoy FreeBSD. ymmv.

* Linux (topic of discussion) * BSD derivatives: * FreeBSD / NetBSD / OpenBSD / DragonFlyBSD * Illumos (opensolaris) derivatives * SmartOS / OmniOS / OpenIndiana * Minix * more[1]
