Well actually, I'd be quite happy to see the Prime make good use of color. I am rather hoping that HP will make, what i call, *proper* use of color:
What i've noticed from the color offerings from TI and Casio is color being used simply to display picture images for somewhat trivial purposes such as the background when plotting a parabola.
I gave a presentation last October at the HPCC conference in London on the potential use of color LCD screens for the display of mathematical clarity. This is what i think is the real use of color on a calculator, together with improving graphical information.
The new color calculator screens are rather like those on mobile phones some years ago. You'll recall that phones quickly made use of these to improve the display of text. However, im seeing existing color calculator offerings display the *exact* same text as before and not making any use of anti-aliasing, sub-pixel positioning, font scaling and kerning.
It's really about time we saw the decent display of math formula on a calculator screen. it's quite possible on the hardware, only the software is missing, and as time goes by, its omission will become increasingly embarrassing.
