I have an HP 50g in my power for several years and I love how flexible it is in terms of tools, however I have also done some time now one Classpad 330 and TI-Nspire CX CAS and is difficult to avoid comparison between other. Anyway, I was watching some videos on youtube where they make different comparisons and found one of them specifically in the comments which said that the HP 50g was much slower than the Nspire thus I decided to confirm it for myself, and I found that yes indeed and not only that, but even incomplete to some extent, and the prime example is this to compute the Taylor series of degree eg 50 or
taylor (sin (x2), x, 50)
this calculation on the Nspire is calculated instantly and complete until the end of grade 50 while the HP 50g takes several seconds and let it surprise incomplete until the term grade 18! Another case was to try to calculate the eigenvalues and eigenvectors of a matrix of 5x5 for example and I figure Nspire immediately while the HP 50g did it in about 3 seconds. In this case is not so serious but relative to the first yes, for even complete all the terms of the answer, and I am surprised because the processor is quite fast HP 75 MHz, while the Nspire runs at 133 mhz but I think use a different operating system but still the tests I've done the Nspire wins. I do not know if any user found where the HP faster but it would be good to know, if in fact it has lagged or other gains in other calculations.

In article <3d8e9741-67e9-49f5...@googlegroups.com>,
Does the Nspire allow you to work in RPN?
Not having to give that up is worth quite a bit!

this is a warning, not about whether the Nspire has RPN or not, to make calculates the HP 50g gives an incorrect result! Leave the answer in the end with grade 18, when asked to go 50 grade! I really like the HP 50g by this calculator has Multiple Solver, Equation Library, programmable keyboard, sd card, etc, but the CAS deserves an urgent review and could fix these problems on an upgrade from version 2.15 was the last. It is important to check these things in the new model HP Prime that comes with these failures and bring the CAS is advanced as is the Nspire CAS.
