TI-Nspire
This page is referring to the TI-Nspire series of calculators, not to be confused with TI-Nspire (calculator).
The TI-Nspire is a series of graphing calculators produced by Texas Instruments from 2007 to present day. It's a departure from TI's past calculators in that it uses a document-based operating system, and computer-like interface with a keyboard (and later on, touchpad).
OverviewEdit
TI-Nspire and TI-Nspire CASEdit
The initial models of TI-Nspire calculators (retroactively known as the "TI-Nspire with Clickpad") used a keypad with arrow keys, like previous models. It was also bundled with a 84 Plus Keypad, mimicking the button layout of the TI-84 Plus. When attached, it will boot the calculator into an environment that simulates that of the TI-84 Plus Silver Edition.
In 2010, the TI-Nspire with Touchpad (as well as a CAS variant) was released. An attachable keypad with the could be purchased for the original TI-Nspire that replaced the Clickpad with the new Touchpad. The TI-Nspire CAS with Clickpad was unable to be upgraded.
TI-Nspire CX and TI-Nspire CX CASEdit
The TI-Nspire CX and TI-Nspire CX CAS released in 2011, bringing a much thinner design, faster processor, rechargable Lithium-Ion battery, and color screen. Aside from that, it acted mostly the same as the previous TI-Nspire with Touchpad. All TI-84 Plus compatibility was discarded.
TI-Nspire CX II and TI-Nspire CX II CASEdit
The TI-Nspire CX II and TI-Nspire CX II CAS released in 2019, bringing new color shells (depending on the region), and a faster processor. Operating system upgrades were cut off for the Nspire CX models in favor of these. Other than that, they act mostly the same as the previous CX models.
