It’s been a good year or so since the TI-Nspire line of graphing calculators got a refresh, but that was nothing compared to what the company’s planning for this year. Possibly responding to changing times (or the Casio Prizm), the new Nspire devices are getting a WiFi dongle for communication with TI-Navigator workstations, a 16-bit (320 x 240) full color display, and a number of new functions, including the ability to load images and analyze images for such things as curve fitting functions and regressions. Perhaps even more exciting, the new Nspire OS 3.0 features 3D functions — and, yes, the original grayscale TI-Nspire models will be able to upgrade to the new OS when it becomes available this spring. Tech Powered Math is reporting a mid-April release date, for an MSRP of $165. Totally psyched? We bet you are! See the PR after the break for more info.
