To all,

I am surprised at the lack of dissenting opinion on this thread. Let
me have one. With all due respect to technoprogressives, I hope the
push button brainless version doesn't show up until I retire. People
in the service bureau industry make a living on the cost and
complexity of the equipment envolved. I like my job. Sorry Elaine.

To Larry Blasch, etc.

Regarding "friendly designs" in general, according to Don Norman in
his book "The Design of Everyday Things" the one sign of a good design
is the ability to use it correctly without any instruction. For example,
those solid glass hotel doors that don't have a handle require you to
push on one side or the other and you have a 50% chance of being wrong...
those are bad designs. It should be obvious how to use the device. There
should be no need to be a techie. And, I believe that applies to RP
as well. As long as we are shooting toward this "user friendly" goal
then we have a chance to make the machine usable by everyone. When we
use the excuse that other machines are hard to use, we miss the point. They
are bad designs.....Let's not emulate them.
