I tried FreeBSD a couple of years back, and X Windows seemed buggy. I mean, come on, this is something that should have been sorted out by now.

Maybe if one were into speed and minimalism, and didn't want a GUI, then one of the BSDs is a good idea. At the time I thought it was slower than Slackware, according to my completely unscientific evaluation. Linux may be more complex than the BSDs, but remember, a lot of resources get poured into Linux.

I'm glad that the BSDs exist, I'm just not particularly inclined to use them.
