@Krik For my personal devices, i use the names of the 12 Colonies of Kobol from Battlestar Galactica. So I currently have 2 laptops: Aerilon and Caprica. When I get a new phone, I'll probably name it Scorpia or Tauron.

Choosing a good naming scheme depends on how many you need, and how often you add to your collection.
