I name the machines on my network with solar system names. Main machines, laptops and desktops, get a planet name. Lesser machine, like Raspberry Pis, etc, get the names of moons. Some people use the names of the seven dwarfs (Sneezy, Grumpy, etc). You can use any set of themed names you like, but it's less typing if the names are short.
To answer your question, my daily driver prompt is "r-w@earth".
