lol, I can understand that caps lock would be missed if you're actually using it a lot. For me, caps lock is the first key I disable when I get a new computer - I make it into either ctrl or shift. It's so extremely annoying to accidentally touch it. For me, what's important is vertical bar (aka pipe), -, _, {}, ; and the like. Which just goes to show that it won't be easy to please all parties (the holding-down for two seconds to get caps lock would be the ideal solution for me, but clearly not for all people).
