Online TI-83 / TI-84

Currently in Beta testing, but still... If you can't find your calculator or someone has borrowed it, this might be a good alternative.

Actually, it's no longer in beta; it's a full emulator now. It even emulates TI's new color-screen TI-84 Plus, and I'm sure you iDevice fans will enjoy the fact that it works (albeit slowly) on the iPad/iPhone/iPod Touch (news article).

It's an amazing alternative; It's a tad too slow on the iPhone but useable as a calculator on both devices. I do the mobile site maintenance for the website it's hosted at but we're in the middle of some back-end work so I'll get full template support for it hopefully next month!

I bet you had a huge guest hit-count after I posted this?

Not as huge as when Hackaday and LifeHacker featured it, but sufficient for me to notice.
