No suspend/hibernate (suspend is available, but fiddly and does not work with X). Apart from that I've been quite happy to this day since last January when I moved to FreeBSD. Though I intend to check-out OpenBSD when I'll have time, as AFAIK it is more laptop-friendly (has working suspend and/or hibernate).
The BSD land is better than any linux distro with its docs and community, and the OSes are really clean and well put-together from the bottom up. Only Arch can come close to them, but then it has no stable releases and breaking changes are often.
BSDs run nearly all the software that GNU/Linux runs, and ports tree is exhaustive. I only have Emacs and Xombrero that I build and install seperately because I'm patching them.
