Voyage 200 vs. TI-Nspire CAS[edit]- Larger and higher resolution screen, color LCD in the CX models, compared to the Voyage, making graphs more detailed, especially in 3D.
- The Nspire user interface has more similarities to traditional PC interfaces, for example: To copy, press Ctrl+C, like in a computer. This simplifies the learning curve for some users. The V200 also works like this.
- Students create and save all of their work as documents with notes, thus enabling teachers to see problem-solving techniques and assess individual student understanding. These documents can be sent to other handhelds, or to a PC, where they can be edited or printed using the Nspire software.
- Symbolic mathematics templates on the input as well as output, or "PrettyPrint" - the ability to show the results as they would normally be written. The Voyage 200 and TI-89 did this to output, while input remained standard.
- More powerful compared to the Voyage 200. The Nspire can handle bigger matrices, a broader selection of equations and functions, all more quickly, since the processor is more powerful and more RAM is available.
- Space – the new CX models have up to 100 MB of user memory and the grayscale Nspires had about 20 MB of user memory, compared to the TI-89 Titanium and Voyage 200's 188 KB RAM and 2.7 MB Flash ROM.
- Graphing has been updated, giving users the option to derive or integrate a function in-graph.
- There is a spreadsheet function which is similar to a list editor. Data from spreadsheets and lists can be analyzed and graphed.
- Data and statistics functions have been improved.
- It is possible to view several pages of data at once, effectively splitting the screen between each page. The user can interact with any portion at a time.
- The newer versions of the Nspire OS are capable of opening files that contain images.
- The Nspire has a new Vernier DataQuest function which can be used to collect data from any sensors connected to the Lab Cradle, which allows up to 5 sensors, or one sensor probe can be connected via USB port on top of the handheld.
- The V200 and TI-89 can solve many algebraic equations, and data input on the TI-89 can be easier for the user than the Nspire.
- All versions of the V200 OS can graph in 3D while this was introduced in an OS update for the Nspire.
- The TI-89 and V200 have better programming capabilities – their built-in language has more I/O and graphics commands, and they also support native assembly programming. The Nspire only has C and assembly support through the jailbreaking program Ndless.
- Third-party apps using native code (like ME*Pro and the Symbolic Math Guide (SMG)) are not available on the TI-Nspire, but newer versions of the OS can run Lua scripts.
- The Voyage features a full QWERTY keyboard, which makes programming and other text input easier for the user. However, some tests do not allow calculators with a QWERTY keyboard.[2][18]
