I've got both ti89 and hp50g. I seldom use the latter anymore.
TI-89 is slick, fast, responsive, a pleasure to use, something to study for its great UX.
HP50g is sluggish and a chore to use. It doesn't deserve the reputation.
This is particularly sad as the hp50g uses a relatively fast ARM cpu, whereas the ti-89 uses a plain 68000.
