I have yet to see a single attack on sshd on that non-standard port. So, while nmap can indeed make a good guess at what service is running on a given port, I see no evidence of attackers actually using that feature. Maybe it'll come later, I don't know, but for the time being I have no reason whatoever to run sshd on port 22 on any of my boxen.
I do that too, I'm the only one who should be attaching to my machine. It certainly keeps your logs a lot cleaner and easy to read.
I also have this in my /etc/hosts.deny ALL: .tw, .cn, .hk, .kr, .pk, .th
