"We're not exactly sure if Texas Instruments' widely utilized TI-83 / TI-84 line of calculators have reached the same success as Casio (but it's fairly safe to assume a \"yes\"), but the firm is finally throwing out a substantial update to the graphing calculators that you, your folks, and probably your grandparents all used throughout high school. The TI-Nspire lineup maintains the same relative form factor, but offers up a few swank advancements such as multiple representations, \"grab-and-move\" functionality, resizing, dynamic linking, and of course, the oh-so-sweet ability to save and edit in-progress work (shown after the jump) right on the device. Additionally, Windows / OS X software will be available to mimic the on-screen abilities of the handhelds, which means those days of viewing the monochrome display via an overhead projector are long gone, and for those who just aren't willing to make the transition, TI is even including a snap-in TI-83 / TI-84 Plus keypad so you can upgrade your machine without relearning keystrokes. The TI-Nspire and TI-Nspire CAS are both slated to hit instructional dealers this Fall for educators (commercially available by Fall 2008), so we'd suggest pinching those pennies now in back-to-school anticipation."^^<http://www.w3.org/2001/XMLSchema#string>
