I have ordered a blank white HHKB with the red esc key and the blue WASD keys. It's out of stock until 10th so a lot of suspense - being in Australia it will be a couple of weeks before I get my hands on it.
Anyway, I am not a gamer, and the WASD keys look good and add a bit of colour to the board, but really the arrows are quite irrelevant to me. What would be good is if I could put the arrow keys either on H,J,K,L (the vim cursor keys) or on [ ; ' / (the HHKB cursor keys). Looking at
http://geekhack.org/showwiki.php?title=Topre+Realforce+Reference+-+all+things+topre#The+keys , it shows the profile of keys and how they are differently shaped for different rows. Looking at that picture again, I'm fairly sure that the answer to this question will be no, but is there any chance the qwerty and asdf rows use the same keys, meaning that I would be able to have HJKL instead of WASD ... else do the asdf row and the zxcv row use the same keys, meaning I could have [;'/ instead of WASD?
I'm fairly sure the answer is no unfortunately. Which makes me wonder, why don't they make HJKL cursor keys or [;'/ cursor keys instead of WASD, as this is not a board aimed at gamers afaik.
