TI-89 or TI-89 Titanium?

<p>I'm really torn between the two calculators. Although I prefer the looks of the TI-89 over the TI-89 Titanium, the TI-89 Titanium has more to offer (mini-USB port, updated CAS/implicit differentiation, more flash memory).</p>

<p>The TI-89 is cheaper and better looking, but I'm wondering if the extra features of the titanium edition are worth it.</p>

<p>The memory will be used to store programs. On my TI-84 regular edition, I am to the point where I have to delete old programs for new ones. But since the TI-89 can do so much without the needs of programs, will the TI-89's memory suffice?</p>

<p>I borrowed a TI-89 Titanium from a friend... but honestly I didn't even know there was a just TI-89. What is the price difference?</p>

<p>I know someone who can sell me a TI-89 for $60. If I were to go with a TI-89 Titanium, I'd probably end up buying it for $90 online.</p>

<p>Anything a TI-89 can do, Mathematica can do better.
If you're looking for portability and ease of use, scientifics are the way to go.
(Never could figure out how to use them graphing calculators.)</p>

<p>The extra features aren't worth it if you're just using it for BC Calc or something. I have a Titanium (because the local Staples only sold those!), and I had to shell out extra money for a bunch of features I'll never use! It's pretty, I guess.</p>
