Why are the HP Prime and HP-35s so unpopular?

Both functions were entered as equations, then integrated. The 32sii finished in about 7.25 seconds, and the 35s finished in about 10.25 seconds....about 40% longer

Instead of entering the functions as equations, try entering them as RPN programs without using any explicit constants, i.e.: do not use, say, the constant 1 as a program line, use RCL 00, and so on with all other constants, then store the constants in the registers and try the integration procedure again. It should run much faster.
