Yeah, it's a calculator.
To be honest, it's not very interesting, but that's to be expected, since it's a calculator. We all pretty much have one, so, naturally, this wouldn't be much of a blowout.
However, it terms of quality, I'd say this is a pretty darn good calculator, except for the 7-8 glitch mentioned in one of the other reviews. Plus, the skin looks sharp too, much better than the one on Windows. If you play around with it, I think you could make something even better. Try making some sort of conversion calculator (like the NG calculator in the Gadgets section).
Best of luck!
