Is TI-Nspire technology meant to replace any current TI educational technology?
No. The TI-Nspire handhelds and software join our current line of leading graphing calculators to provide educators with additional options to meet the differing needs of classrooms. The TI-73 Explorer, TI-83 Plus and TI-84 Plus families of graphing calculators, and TI-Navigator classroom learning system are research-based technologies that will continue to be a strong solution and for math and science classrooms. These products will continue to be supported with professional development, classroom activities and other resources.
