I moded my cherry G80-1800 to a combination of cherry black switches with cherry brown springs. I love it's tactile feel so much.
What I don't like is it's layout.
A unix layout would be much better for me ("Esc" key swapped with "~" key, and "Backspace" swapped with "\" key), because I am using Emacs + viper on a Mac.
The solution could be buying a HHKB lite 2 or a HHKB pro 2. But I am not sure if any one of them would be as good as my current keyboard. Besides I do like my current keyboard, it's kind of waste to buy something else and put this up on the shelf.
I also tried softwares to remap the keys, but no solution actually works on Mac. Xmodmap works great, but it only works for applications in X11.
Any suggestions?
