This is the future of Texas Instruments handheld calculators:
What is the TI-Nspire CAS+ handheld?
The new TI-Nspire CAS+ math and science learning handheld, designed for pre-algebra through calculus and biology thru physics, allows students to see and edit multiple representations of a concept - all on one screen. This enables students to more effectively and easily explore relationships and make connections.
With TI-Nspire technology your students can electronically create, save and reflect on every step of their work. This gives them the ability to review, demonstrate and communicate their problem solving – and you to assess their progress, even toward meeting curriculum standards.
Carrying forward the core capabilities, including the Computer Algebra System (CAS) of TI-89 Titanium graphing calculators, the research-based TI-Nspire CAS+ also adds:
- Interactive geometry software that integrates with algebra explorations
- The ability to grab and manipulate graphs & geometric shapes to see real-time changes
- Drop-down menus for easy, intuitive operation
- Software version for computer lab use or for classroom demonstration
What is the TI-Nspire™ CAS software?
TI-Nspire CAS computer software is computer software that incorporates the exact same capabilities of the TI-Nspire CAS+ handheld on a computer. The computer software provides opportunities for students to access TI-Nspire technology in a computer lab environment. As a tool for teachers, TI-Nspire CAS computer software acts as an emulator for effective classroom demonstration.
Where and when will the TI-Nspire CAS+ be available?
The TI-Nspire CAS+ handheld and TI-Nspire CAS Software will be available in 2007 through select Canadian dealers. Please call 1-800-TI-CARES for updates on purchase information.

Lockheed’s shiny new F-22 Raptor stealth fighters may have owned a few war games, but crossing the International Date Line left them as helpless as a carrot in a rabbit trap, with multiple system crashes causing an emergency detour en route from Hawaii to Okinawa, Japan. Communication, fuel subsystems, and navigation systems were rendered useless and repeated "reboots" were of no help. Luckily, the fleet had clear skies and refueling tankers to guide them back to Hawaii. If they had separated from the tankers, "they would have turned around and probably could have found the Hawaiian Islands. But if the weather had been bad on approach, there could have been real trouble," states Retired Air Force Major General Don Shepperd. The voyage suffered a two-day delay on account of the system failures — "a computer glitch in the millions of lines of code, somebody made an error in a couple lines of the code and everything goes." What should have been a showy parade of $125+ million super fighters quickly turned to disaster for Lockheed who would’ve had a lot of explaining to do, had this happened during combat.
