My first Amazon review in years

[yendi]

I haven't bothered reviewing things at Amazon in ages (ten years, in fact!), mainly due to time. But in light of how well Elayna did in math this year, reviewing the calculator that saved us a good $60 felt like something worth doing. Elayna still raves about this device.

(I'm sure some of the engineer-types I know have some damned good reasons why the TI is still better, but for Elayna's needs, this was amazing.)
