Other subatomic particles sound cool too. I think theoretical physicists are just the best namers around.
Though while neutrino's are the smallest known particle, there are also Protons, Neutrons, Quarks, Muons, and so on.
In my case (and originally i wrote it) neutrino is also build server at my work and dj from radio, which i listened to, when starting to write new robot. So it's largely just a case:)
