I tried, but hardware support in the BSD world was frankly pathetic. NetBSD doesn't support ACPI suspend-to-disk and needs special kernel configuration just to show readable characters on the framebuffer console, on my old laptop. FreeBSD and NetBSD wouldn't even finish booting on one of my systems -- a run of the mill, 12 year old amd64 desktop PC that never had any problems with Linux.
I haven't tried OpenBSD lately. Although it's really high quality, its upgrade schedule is unacceptably hectic for me. I like stability on my systems; whereas, with OpenBSD, you must reinstall the whole system at least once a year, if you want to keep it secure (and if you don't, I don't see why you're running that particular OS in the first place). What OpenBSD really needs are long-term support releases.
What the BSD world needs is BETTER HARDWARE SUPPORT if they ever want to be serious, viable contenders. I'd love to switch away from Linux, which is getting more and more fragmented and unstable. But the simple fact is that, today, there is no serious alternative in the Unix[-like] world.
