Let me tell you if I could type on my Model M's for any length of time.
cf my long standing argument that unicomp needs to engineer a 'lighter bs'.
my ideas:
--one version with lower spring tension, the light switch version.
--one version with the spring/materials redesigned so that it buckles but doesnt click. (tactile but not clicky).
come on unicomp, are you listening?! ;-D
