An anonymous reader writes: Texas Instruments has just unveiled its next generation of graphing calculators the weekend with the TI-Nspire. TI calculators are famous not only in the educational arena but also with the hobbyist hacker crowd around the world because of the ease (or some would say complexity) of which it is to develop for them. The TI-Nspire comes in both CAS (computer aided algebra) and non CAS flavors, and as an added bonus, the non CAS models even includes a fully functioning TI-84+ compatibility mode using a replaceable TI-84+ keypad (which is sure to come as a delight to 84 hackers and gamers everywhere). It packs 20MB of storage and 16MB of memory, an ARM based processor, a 320x240 grayscale LCD, and a USB port. The TI-Nspire should be out in the fall to specific dealers, and in retail stores by early 2008, just in time for back to school in 2008.
