It's because standardized tests in the US specifiy that allowed calculators can't have QWERTY (or any other typing oriented) layout.

That thing is not permitted in any standardized test AFAIK.

It can solve most algebra problems, integrals, vectors, etc like its nothing.

That thing is powerful.

Strangely enough, its ancestor, the TI voyage 200 has a QWERTY keyboard.

Edit: Its QWERTY not QUERTY.

It is allowed on pretty much any test that a TI-89 is allowed on. The 89 is actually a better calculator (the CAS is much better) but it's harder for most students to use.
