I would love something like this to become standard, but I recall needing a specific calculator in HS. Our math classes were based on the TI-83, and people with an 84 or 86(?) would struggle because the interface isn't exactly the same. Maybe there is more variety now and classes can better handle other calculators.

My wife is still using my old TI-89 about 20 years later, but if that ever dies I will probably pick up something like this for general use. I would also much rather my 6-year-old learn python instead of spending her time making goofy games in TI-BASIC like I did.
