Re: TI89 very slow !!!
I own both, an HP48GX and a TI89. I've used the HP since 1994 and really
liked it. However, its overall speed started to get to me. Truthfully,
it's quite slow overall. I just got the TI89 a week ago, and love it. It's
fast. Just try maneuvering around the HP48GX and you'll see how sluggish it
is.
I tried some summations, differentiations, and integrations on both the
HP48GX and the TI-92, and about 90% of the time (depending upon the
functions) the TI-89 was quicker.
