Should I stick with my TI-Nspire CX II CAS or get a TI-89 Titanium
Some context I'm in high school currently and around the start of my school year last year my sister ended up giving me her old TI-84 Plus and that basically start my love for TI calculators as I really enjoyed just getting to learn about all the stuff you could do with them and just the charm of it too I fell in love with as I really like tech similar to it and with some time I started to really want to get the TI-89 Titanium as it has so many more different and exciting features while still having the charm of the older TI-84 plus and during the time I was looking to buy a TI-89 Titanium I found a TI-Nspire CX II CAS (used) for a really price near where I lived and I knew how much better it was so I decided in the end to go with it and for the past little under a year I've been loving it and enjoying it but I still feel like something is missing as I feel like it just doesn't have the charm as the older TI-84 Plus that drove me to love them
And so basically what I'm getting at is would it be a bad idea to sell my TI-Nspire CX II CAS and get the TI-89 Titanium or should I keep the TI-Nspire CX II CAS and continue using it and learning about it.
