it's an idea.. with my computers I went with names that didn't really have meaning. magnesium for my thinkpad because it's frame is magnesium, carbon for my ThinkCentre.. because it's black, lithium for my primary desktop for no good reason it just sounded nice, aluminium for my mac because it is silver, calcium for my home theatre computer because it is white, and the wireless networks because they are noble gases and I thought that was fun.
I was trying to find an elemental name that started with a P but none of them sound like much fun. If not a P, it needs at least a fun personable name.
