This is a very stylish and fancy looking calculator. At first it appears to almost look like a very low end smartphone. When I first saw this device it looked very impractical and a bit too flashy for my tastes, however it has it’s good points. Especially it’s battery life. It has a 140 hour battery life, running on 4x AA batteries, which means you could pretty much leave it on all week before the battery dies out. The Casio Prizm may not be their crown jewel of devices but it is indeed very nice. I do not think many kids will really need a device like this, but it does at least get the job done, graphing and calculating your problems. At the very least you can pretend to have a very cool phone, given you only let your friends see it once and only for a few seconds.
