The world's best keyboards. I'm talking about the IBM buckling-spring keyboard that clicks twice for every keypress to make it sounds like you're typing really fast. It also provides juuuust the right resistance on the way down to keep your fingers from think they've been stabbed into a wad of week-old marshmallow all day long. They're also huge and heavy, keeping them from sliding all over the desk; and if you throw it at something in frustration you can be fairly certain that the target, not the keyboard, will break. You can have mine after you pry it out of my cold, dead, fingers.
Update: I have the 12 foot cord. I guess that makes me cool or something. For me it just means I can pick up the keyboard and walk across the room with it...
I also got a newer IBM keyboard that weighs about half as much as the originals. Still has the nice clicky action though.
