Texas Instruments recently rocked the graphing calculator world by adding a touchpad to its TI-Nspire calculator, and Casio has now come back with a technological revolution of its own: a high-res color screen. Of course, a 3.7-inch, 384 X 216 display may not be much by smartphone standards, but Casio insists that the "Blanview" LCD will let equations and text be "displayed just like they appear in textbooks." The rest of the calculator's specs aren't too shabby either, and include USB connectivity, 16MB of flash memory, and a promised 140 hours of battery life. You'll still have to stick to your cold, hard black-and-white world for a while longer, however, as the Prizm won't be available until sometime in January, when it'll set you back $129.99.
