I've been meaning to make a note of this for a while now. I've been a happy hacker keyboard user for a while now, I really like it. I really like the lack of a caps lock key. To get the same effect on a normal keyboard under linux you could use the following .Xmodmap

 !
 ! Swap Caps_Lock and Control_L
 !
 remove Lock = Caps_Lock
 remove Control = Control_L
 keysym Control_L = Caps_Lock
 keysym Caps_Lock = Control_L
 add Lock = Caps_Lock
 add Control = Control_L

Or if you don't want the caps lock any more

 !
 ! Swap Caps_Lock and Control_L
 !
 remove Lock = Caps_Lock
 remove Control = Control_L
 !keysym Control_L = Caps_Lock
 keysym Caps_Lock = Control_L
 !add Lock = Caps_Lock
 add Control = Control_L

or else do setxkbmap -option “ctrl:nocaps” for something less permanent.
