I have this thing called a TI-83. It works well. It sits by my computer. I tried this but it is not the same, TI-83 STILL has more features, and it is MUCH older.

I just tried it, and it's not bad, but Wolfram Mathematica owns it (but it's not free). Hell, even Wolfram Alpha is more useful to me, hehe Will keep it installed for a while, though Thanks for linking that

They're good. I still don't understand why it's so hard for everyone to do anything even remotely as good as those things, but for phones.
