Hey , my slide rule works just as well as it did 32 two years ago. If you
look closely at current technology the HP50 is a relic! I am running Derive
6 on a Fujitsu life book (with the 49 emulator). The point is that battery
life only trades so far and going after a bigger market would address more
powerful features.

It takes a pc to run Maxima, an open source alternative to Mathematica.
Maxima recently has been used to demonstrate mathematical errors in the
theory of General Relativity(GR) that were made in proofs of the
existence of black holes. Eg, black holes actually are impossible
according to GR. It now appears that much of cosmology theory is in
tatters, although this can be demonstrated only by using programs like
Maxima and Mathematica. I still like my HP48 though.
