My laptop's hostname is rei. Guess what, my tower computer's hostname is asuka. Well. You can guess what inspired me :D
Hmm. I broke that line of naming shortly after. I named my home application server eve.
Last but not least, I decided on the name mei for my smartphone after a very long time thinking about it.
All other devices are not special enough to carry a special name, so they are just called me1, me2, me3, etc.
