Well, since I am a taxpayer, than I can use my taxes appropriately, I suppose.
However, I still argue that it's on the government's dime, since we're running such a huge deficit, taxes only cover a small portion of it. Anyway, I really don't feel like getting in to a political debate over the issues.
Besides, with the type of hardware we use in my lab, it's actually cheaper to buy a Unicomp Model M or a Filco, and then reuse it with each new machine. Dell charges an arm and a leg for input devices when you buy their high end stuff (relative to their quality, anyhow). An extra $60 for a keyboard and mouse when you buy a workstation from them?
Also, it turns out Unicomp will even give custom layouts for only a small upcharge, which does us even more of a favor, since UNIX style keyboards are what everyone here wants.
