Back in high school, your TI-89 was your best friend. Well at least in math class. Or maybe most elsewhere too.
That's why my TI-89 still sits on my desk, and on occasion gets picked up and graphed upon, too. But today I came across a nifty Android app that purports to put that calculator right in my pocket, right in my Android phone. Yes, the TI-89 emulator, aka Graph 89, has graced the Android Market and made its home in my phone.
