A colleague uses a Sculpt, so I did try it, but the key travel is such a long way from my (wearing out) Logitech Cordless Desktop Pro: that's from about 2004, and has tall keys [1].

Perhaps you could use a tiny widget that shows the caps lock status next to the clock?

I ordered Cherry MX Browns, which seemed like a fairly standard choice — red for gamers, brown for typists. I just hope they're not too loud.
