BTW, the Prime is $50 more expensive than this thing and doesn't have the exam mode -> illegal to use in exams in France, for ex.
I think that any advantage of being able to run python is moot considering that it has only 256KB of RAM.
And for high-schools, personally, I think something simpler and less expensive would be nicer.
And I also wish there would be a calculator more targeted at engineers.
For something smaller, there's the Swissmicros DM42. That one is definitely an engineers tool, but it's exclusively RPN. It's basically a super modern HP 42s with a huge, georgeous screen and a USB interface (and a modern ARM MCU). The software is based on the excellent Free42 project.
