Step by Step calculations

[parisse]

I'm curious to know what features of the CAS you find better on the classpad then on the Prime. I don't have a classpad 400, but the classpad 330 CAS is considered by many way inferior to the nspire CAS and Prime CAS.

The CP400 does indeed have inferior hardware compared to the Nspire and Prime, its CAS is usually regarded as inferior, its BASIC was shown to be horrendously slow (as in, two orders of magnitude slower than the TI-Z80, TI-68k, TI-Nspire, HP-49g+/50g, Casio Prizm) on simple operations in high school level problems, and adding insult to injury, the CP400 is very expensive...
