Proving again that water and keyboards don't play well together, I needed a wired (USB) keyboard and was rather stunned to find only wireless models at the local Walmart. So off to Amazon I went and found all kinds of keyboards at all sorts of price points. I settled (happily) for the $12 "manhattan" brand shown below.
Is it any wonder that computers scare people when they see 104 keys including 12 Function Keys, and all those Ctrl, Alt, and Shift combinations? It's like you have to learn a second language to use them.
