The TI-80 line of calculators has a very easy-to-learn interface, and this is probably the reason it has become the de facto standard calculator in highschools and colleges across the country.
But would someone please tell Texas Instruments that it's 2009? We don't measure processor speeds with double digit MHz anymore, nor do we measure ram in kilobytes. Not that they need to use world-class hardware, but on the TI-84+ it takes about three seconds to graph sin(x). If my similarly priced nintendo ds and slighly more expensive iphone touch can render 3d graphics in real time, why can't my calculator graph sin(x) in less than 3 seconds? I think for over $100 dollars, Texas Instruments could make a much faster calculator (and a higher resolution screen wouldn't hurt either).

This calculator works great. I haven't had any problems with it. I think it was a perfect purchase for a great price.
