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.
