Which do you guys think is better? The HP 49+ or TI-89 Titanium? This is kind of an important thing to me, because I'm thinking of buying a new calculator, but I want it to last and be good. I'm going into AP BC Calculus (the hardest at my high school), AP Physics, and AP Chemistry next year, and I also want it to serve in my future college math and science classes (including more calculus, Multivariable Calculus, Differential Equations, etc. b/c I'm going into 'Red' Biotechnology). I'm looking for power, speed, overall capabilities, expansion (I know the HP 49+ has a SD port, but does anybody know up to how many MBs or GBs it goes to?), and of course, games.

I would have to say TI89 titanium because it is more user friendly. If you can figure out the HP49G+ I think you have more capabilities. I have never actually owned or used a HP although I probably will buy one when I have some extra cash. I think the HP49G+ shows you the steps when doing derivatives. I know a couple guys that have the HP and neither one knew how to use the calculator more than I could us my TI89 titanium. I love my TI89 titanium so much that I emulate it on my computer when I write programs for it.

How to emulate TI89 titanium.

I have/had a nice series program for the TI89 titanium and one for integrals by substitution. I will post links to download them or you can go to http://www.ticalc.org and search threw the files.

Series Convergence Program: helped me make a good grade in Cal 2. :)

Integration by parts, not substitution, been a while since I have done Calculus...

These are two good programs for the TI89 although the series convergence one is so much more powerful.
