Craig, I agree, the F-1 functions may not be considered intuitive, unless you understand that they represent the inverse or complement of the F function associated with the key. But I personally prefer the method that HP chose on the 65, it makes for a cleaner keyboard with fewer labels and it assumes a somewhat higher level of mathematical sophistication on the part of the user.

We had a discussion of this point back in 2011:

I agree. There was a time when a product owner/user was expected to have a certain level of knowledge/sophistication.

I am a watch collector and often bristle when a watch dial (on luxury watches even) state both metric and feet for water resistance. If it's 100m, just say 100m for goodness sake. I can do the math.
