Why FreeBSD
An anonymous reader writes "The FreeBSD operating system is the unknown giant among free operating systems. Starting out from the 386BSD project, it is an extremely fast UNIX-like operating system mostly for the Intel chip and its clones. In many ways, FreeBSD has always been the operating system that GNU/Linux-based operating systems should have been. It runs on out-of-date Intel machines and 64-bit AMD chips, and it serves terabytes of files a day on some of the largest file servers on earth."
FreeBSD is for people who hate Linux.
OpenBSD is for people who like Unix.
If you want a BSD, then you want Open. FreeBSD is a bit pointless, it doesn't really do anything well like OpenBSD, it's just more fashionable and mainstream so wannabe-geeks use it who think they're too elite for Linux.
