Mechanical Keyboards

I like the Filco ninja keys, as although I touch type pretty fast, when I'm tired I still hunt for the rarer keys like ^|¬

Ninja/blank keys are just to wind up wife/daughter if they try and use it. I never have to look at the keys, even the obscure ones, once I'm used to the keyboard. I'm coding a lot of the time so I do use pretty much every symbol at some point in a day (or in one or two lines if writing perl). Haven't checked typing speed for years but last time I did was somewhere around 140wpm.
