Today, Casio released OS 1.03 for the Casio Prizm (both fx-CG10 and fx-CG20, unlike the earlier OS update). It fixes the well-known "Locate glitch" that causes displayed characters to be colored wrong, and also several other glitches that have been reported to Casio by the community. Unlike TI, it seems like Casio are actively fixing glitches, no matter how minor they are. OS 1.03 also adds supports for the new Physium add-in, which is a periodic table.
Editor's Note: Thanks to JosJuice for finding and sharing this. To read more about the contrast between Texas Instruments' recent treatment of their loyal community and Casio's attitude towards their newfound converts, read Cemetech's well-shared editorial Casio Prizm: Why TI Calc Coders Should Abandon the Nspire CX. Of course, we still are huge enthusiasts of the TI-83+/SE and TI-84+/SE calculator lines, and development continues on many projects for the TI calculators and Casio Prizm alike here at Cemetech, as well as plenty of computer programs and games and webapps. Looking to buy a calculator for fun or school, and aren't sure whether you should go with a TI calculator or a Casio calculator? Cemetech's Back to School 2011: Calculator Guide might help you.
