Ask HN: Best coding keyboard?

I've seen the Happy Hacking Keyboard (http://en.wikipedia.org/wiki/Happy_Hacking_Keyboard). It has the CTRL in the right, UNIX-style place (where other keyboards have the CAPS LOCK key). It also features Fn-key access to function keys and arrow keys near the home row. That's pretty close to my dream keyboard. I'll describe my perfect keyboard, maybe you guys can point me to something close: 1)Apple style flat keyboard 2)No numblock, function keys via Fn-1..0 like Happy Hacking Keyboard 3)UNIX-style CTRL key instead of CAPS, like HHK 4)Fn-hjkl for arrow keys (VIM movement) 5)Backspace/del works like on the Mac keyboard 6)Preferrably programmable in some way, to try out new combinations 7)Quiet, no loud clicking Anyone know something like this?
