This is about a small device which connects to the net and sends text
emails to a single address. There is very little as regards 'menus'.
Would the component power and cost (e.g the processor cost) have to be
significantly higher if one were to substitute a graphical LCD instead
of a text lcd in such a device? I understand that the lcd cost itself
would go up by , say, a factor of 2.5 but would one need significantly
higher processing power etc etc? If so, is it possible to get a very
very rough idea of by how much higher the cost would be?
