Re: ti-86 vs. ti-89
Actually, I'll be waiting till about September anyway, because my dad is a
university professor, and he intends to order bulk amount for his classes
(40), so i will get them at 50 dollars cheaper than a store. (Bulk
Educational Pricing). So if HP comes out with a better calc, i'll buy that.
My dad has a 48-S calc and he bought it for $150 in 1990, and it is STILL
better than my TI-86 which i bought in November 1998. He told me to buy an
HP but i didn't listen.
P.S. I was going to get a G+ anyways
Maybe he does know something after all.................., nah, its just not
possible
