I use the Ti-nspire CAS calculator at school ever since year10. As a result, i am intimately aware of how to use my calculator to my advantage. I am constantly helping others with their calcs. I am currently using Version 1.3 (out since 2008)... others in my class vary between v1.4-1.7
My spesh teacher, however, wants us to upgrade the software to the newest setting: v2.1. I think that i'm comfortable with my version and i seriously hate the layout of the newer versions - i can't navigate them at all. Having said that, though, the new version may have additional features.
So, the question is:
Do i stick with my trustworthy v1.3, confidant in my calculator knowledge to use to my advantage OR
Do i upgrade to v2.1, unknown, unfamiliar, but possibly equipped with better features?
My spesh teacher says that we all must embrace new changes (and stop being stuck in the past), so we may as well upgrade it now so there's plenty of time for us to be familiar with the software before exams.
What do you think?
