Input:
I have a workstation chair with arm rests that support my arms over the keyboard all the way to the wrists.  This arrangement lines my hands and fingers up perfectly with this keyboard.  I can't believe I didn't switch to one of these long ago!  We get programmed that computers have one monitor and a straight keyboard and most of us fail to upgrade to monitor arrays and ergonomic keyboards.  If I didn't have this type of chair I would find that the keys are too elevated for the built-on palm rest.  You may want to somehow engineer a higher palm rest, a common problem with all keyboards I've seen.  I did not find a problem with the half-size arrow keys or 3/4 size Delete, etc. keys, and although I've been keyboarding for over 20 years I'm no typist.
