I have not kept up with pocket calculators since TI-89, so I was pleasantly surprised to learn about the capabilities of the newest member of the TI pocket calculators available since 2019: TI nSpire CX II CAS. Wow! You can program it in Python or Ti-Basic and it has 64MB of operating memory. It's more powerful than my first PC (IBM PS/1 model 2011). Noice!
