Once I discovered Algebraic methods on HP, I became a pretty enthusiastic user. Even with the unary minus confusion of the 32sii, I very quickly found that I could use equations for a huge amount of stuff that I used to program in RPN.
Similarly, when opened my eyes to the other models (17bii, 48GX, 27s) I became a strong supporter of the algebraic solvers and algebraic objects.
Back in the early 90s, if only I'd bothered to look at the Algebraic 27s, I might have left RPN behind forever.
And the 48GX (and 49 and 50) is totally cool with the ability to use agebraics and stack-based manipulation together. The holy grail.
(BTW I am the quintessential HP profile customer: 1st in my school with one, used hp exclusively for over two decades, looked only for hp and rpn when I lost my 11c way back when...preferred (and used!) a slide rule rather than a Ti when I had a repair being made!)
Fractions: I was an instant enthusiastic user of fraction input (but not display) on the 32sii. It goes with the territory (U.S. engineering).
Similarly, I found the unit conversions useful. They save keystrokes which is the whole point. On the 11c, they were printed on the back, which I also think is good.
