The lack of direct P<->R conversion!!!!
The angle symbol that looks like the figure 8.
The display presentation of complex and imaginary values.
The strange behaviour of checksum for program.
Battery life.

/ in daily use: 15LC, 41CV and 35S
/ seldom use: 19BII, 29C, DM16,

Thanks for reminding me: the lack of Real and Imaginary part functions for complex numbers.
