Up until two or three years ago, I was a dedicated Mac-head, but I finally decided that my home setup really needed to mirror my work setup. (I think I mentioned this in one of my 20-things-about-me posts.) I wasn't sure I could handle a PC, since they weren't as user-friendly as Macs, but, to be honest, the Mac system's inner workings had become a mite complicated, too. Turns out I could handle a PC just fine (with occasional help from my friendly neighborhood geek), which was a great relief, and I can exchange data with my work setup without anymore translation.

BTW, big thanks to my most excellent cat-sitter, who always comes through in an emergency. :)
