It's a shame there isn't a perfectly symmetrical 60% on the market.
Someone definitely made an attempt of that: http://xahlee.info/kbd/katana60_keyboard.html
Thanks. I know about that, but it's not what I had in mind. It's not very aesthetically pleasing, is it? Unless you did something with that blocker smack dab right in the middle of everything...
I can't really get over ortho keyboard with an odd number of columns leading to a centered arrow cluster either.
