Texas Instruments has been making graphing calculators for twenty years now, and things look pretty much the same as they were in that bygone era of Amy Grant and C&C Music Factory. The company’s latest, TI-Nspire with Touchpad, features — you guessed it! — a touchpad above the keypad for scrollin’ around, as well as a letterpad (apparently they had to forgo QWERTY to make this compliant with tests like SAT and ACT). And, like its precursors, it comes with a snap-in TI-84 Plus keypad so your old dog won’t have to learn any keystrokes. Available now from your fave e-tailer, look to pay around $140.
