i plan on using the poker layout but changing the key mappings to match a HHKB. for instance, **** the caps lock. control all the way. and i like how HHKB utilizes the function layer.
the reason i hesitate to make a HHKB GH60 is I constantly use the Win Key and the plates/cases will probably be in less demand. Win key is just useful, and i miss it on my IBM Model M.
to each their own.
