Anyone else out there regularly use a TI calculator emulator?
I think it's a neat mix of novelty and practicality that a lot of people are unaware of.
I use a TI-83 Plus and ripped my ROM using TiLP and now use TilEM on my Linux machine and Graph89 (available on F-Droid) on my Android device. The hardest part was getting a hold of a TI Graph Link cable.
The matching familiar layout can sure save time versus learning whatever the landscape version of the default calculator app on your phone has to offer.
I used to do something similar, now I use CalcES on my phone which is essentially an FX991ES emulator with modern quality of life features and graphing. Now I can't imagine using anything else.
