To name something is to control it. I name my devices after minor (and not-so-minor) characters in Hitchhiker's Guide to the Galaxy. I try to stick to the novels, but sometimes venture into the radio or film series. Names in italics are for devices I no longer own, and so I've re-used the name.
Vogon: Nokia N70
Garkbit: iPhone 3G (sold)
Gag Halfrunt: iPhone 3GS (sold)
Veet Voojagig: iPhone 4 as well as the two (!) replacement phones
Trin Tragula: iPhone 5 as well as the three (!!) replacement phones
Lazlar Lyricon: iPhone 6 (which had its screen and battery replaced)
Anjie: iPhone X (which had its screen replaced)
Frat Gadz: PS4™.
Sulijoo: old Linode VPS, also the subdomain I point some CNAMEs to, also now a VPS on Digital Ocean.
I can't actually name my Android device (there's no "Device name" setting in the "About device" section), but I'm going with that.

Lallafa: my personal 2010-era MacBook Air (also .lallafa is the TLD of my localhost, instead of more common .local)
