I hate to be a naysayer here (because I actually like the idea of this calculator) but I use R for virtually every mathematical and statistical problem I encounter. It's always open on my computer while I'm working and I'm comfortable enough with the program that most of the syntax requires little thought on my part.

If I'm in the field and need to perform some calculations, I either use my phone (for simple calculations) or my $17 Casio statistics calculator.

As a risk assessor and environmental scientist, I have NEVER needed anything more than these.

I have a TI-89 emulator in my android phone. I use it all the time from simple calculations to graphing. I think I might have used the calculus functions a couple of times. Anyway, it's really convenient and now I wouldn't even think about carrying around another device that only does what a calculator does.

This calculator is designed for high school students, and it is certified for tests.

I think the days where engineers, scientists and students shared the same calculators are gone.
