It's fully up to date with the latest TI-Nspire OS, version 3.2. This book can prepare you for everything you need to know to get started with the TI-Nspire with a variety of tutorials, focusing on graphing and calculation features. It'll work whether you are on the original TI-Nspire clickpad or the latest TI-Nspire CX. It's very affordable too. The book costs just $6.99 in Kindle format or $9.99 in paperback.
