Before my company merged, they used Sesame Street characters...
Bert, Ernie, Bbird, Oscar, Elmo (was actually a homegrown software program), Snuffy.
Now they use Geo/OS type names... which are boring but informative.
At home... HALxxxx (xxxx = the year I bought the computer).
HAL 1999, HAL2003, HAL2004.
Server is HAL9000.
Although I did just deliniate and named a new laptop Nomad. No idea why.
My SSID is starbucks.
