I have one. It's great. It's quite an amazing bit of tech.

I wish they would split out the market, though, one for the educational market for tests and the like, and one for the professionals with wireless and more open capabilities.

I would like for instance to ship images of graphs to use in a web page. Or to use it as a keyboard to type equations and calculations into documents. Or to have it connect to PyPI say to grab programs that can calculate complex equations.... etc.

I have long believed that there is a huge market for some sort of rudimentary TI-style CAS system, with a caveat. Something that works on embedded arm devices, but is screen aware enough to be ported to a desktop.

If you include bluetooth in your calculator hardware, you now have an excellent input device for an onscreen CAS - or maybe something more like a screencast.

Extend this concept far enough, and we're talking about something like OP is describing - easy to sync and share small programs and tools. Further integration with excel and other tabulated data sources, and you've got a real killer on your hands.

matlab or octave (oss clone) may be of interest to you.

for symbolic math try wolfram alpha, the matlab symbolic math toolbox or one of the symbolic math packages available for python.
