Why do calculator manufactures like to reinvent the wheel?

However if I count it all together I've already worked 3 years in industry so far, all in electrical engineering departments (so it's not like I've worked in production or at McDonalds where it would be obvious that there are no HP calcs around ^^).

Well, that's all I was saying. HP never made much inroads in education, that is what the Prime is about. Actually, calculators were somewhat rare generally when I was in college. Anyway in the areas I mentioned I have seldom seen a calculator that wasn't an HP.

Thanks for the info. I dislike touch screen devices but it also took me a few decades to accept LCDs so I will check back again in 2045 or so and maybe it will be time to reconsider.
