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

Sure. I used the program version on both the 32S and the 35s, because I figured that would provide the most accurate comparison. It's the Bessel Function from page 128, which, if I'm being honest, I don't really understand. This is the program:

Code:

J01 LBL J
J02 RAD
J03 INPUT X
J04 INPUT T
J05 RCL T
J06 SIN
J07 RCL* X
J08 COS
J09 RTN

To run it, I followed the instructions from the manual on both calculators, which are:

Code:

FN= J
0 [ENTER] pi   ( integral limits )
intFN d T
2 R/S   ( set X to 2 and solve )

I ran the experiment again, to verify, because I didn't write down my results last time. The 32S finished in 23 seconds, while the 35s finished in 58, or just over 2.5 times faster.
