Don't waste your money. Go buy an HP 48GX, and a couple memory cards if you really need more than 128k of calculator memory. The 49g is ugly, has no IR port, a very dumb integer value type, and above all, pain in the fucking ass soft keys that often have to be pressed two or three times before registering.

And they moved the Enter key to the lame-ass TI/Casio position in the lower-right corner. You just can't improve on a classic.
