Mostly it's the educational world abandoning everything other than TI because TI has a lock on the US education market. "Us engineering & math types" simply aren't enough of a market to have a say in what type of calculators are made and marketed.

Well, yes, but then those high school pupils graduate and become university students (some in engineering and sciences), but they keep their old TI graphing calculators. They don't switch over to HP once they take up a technical field of study. HP really does need to stay in the educational market otherwise the gig is up long term. If it were somehow possible to gain something in the school market (if not the US, at least somewhere with some volume), then one can eventually build a following.

When I was in high school (35 years ago), not many peers used HP calculators, but people could easily if they chose, before the mathematics curriculum wasn't wrapped around a specific brand / model like it is now. It's a tough situation in the USA for anybody other than TI.
