<p>So I've got a 89 titanium, but I've been drooling over the nspire cas. Any thoughts on if it's worth the upgrade of $60-70? What added features am I really getting? I'll probably major in something using a lot of math. The only big benefit of it that I immediately see enjoying is the hardware; higher res screen, faster, etc. Thoughts?</p>
<p>Wow, hadn't heard of that before...just looked it up and it looks really sweet. I think I'll get one for college maybe.</p>
<p>So if price isn't an issue, why not? But is it really necessary...Like you said, it's basically a fun toy w/ convenient features. Fun!!</p>
