It's impressive how both the feature set and community have grown since then and hard to imagine the OS now giant-locked or without ULE, ZFS, DTrace, PF, and a host of other things both homegrown and imported. I'm particularly excited to see BHyVe mature so there is a native VM option besides VirtualBox when I need more than a Jail.
FreeBSD still struggles in some scenarios, especially desktop use and availability of BSD VPS hosting that would let people cheaply experiment with the OS like they can with Linux on Linode or DigitalOcean. I have a FreeBSD desktop and a VPS running in prgmr.com's Xen environment, but both took quite a bit of effort to set up:

Happy birthday, FreeBSD!
