Think Twice About It.
I found the TI-89 to be unusable because the print was too small to read. Also, my unit came without a manual. C'mon guys, who buys an expensive, complicated piece of advanced technology WITHOUT THE MANUAL???Anybody thinking about spending over $100 on a TI-89 should think twice about it.
