My desktop computer is Homer after Homer Simpson (I once had Homer, Marge, and Maggie for my three HD partitions until I went back to just one partition)
My iBook is named aXel because I lived in Sweden for a year and I love that name, but also because when I was bored one night while studying in Beijing I had a MacWorld my mom had sent and I cut a,l, and e from Apple and used the OS X X to make a name tag for him.
Finally, the iPod is called Lucky because I won it at a tech convention (granted I was working while everyone else was partying on their spring breaks, I got the better deal). I'm such a loser.
