Графический калькулятор Numworks для студентов.

...Physically, Numworks is much smaller than most scientific calculators, weighing just 5.9 ounces with a thickness of 10 millimeters (0.4 inches). It's rechargeable via a micro USB port (a cable, but not a charger, is included), and can go 20 hours between charges under normal operation. When not in use, it can hold a charge for "years" in deep sleep mode. The 2.8-inch diagonal (2.2 x 1.7 inch) screen can display over 262,000 colors.
The keyboard is split into three distinct areas: navigation, advanced calculations and a numeric keypad with widely spaced keys to reduce entry errors. There's also a home, back, and standard On/Off button.
