Ask HN: Are any modern TI calculators as reactive as the TI-84 Plus?

1 points by hereforphone ↗ HN
I have a TI-84 Plus, and had a TI-89 Titanium. I never used the TI-89 despite its feature set because it wasn't reactive. I like to turn on the calculator and immediately start entering data, and that wasn't happening with the TI-89.

I see there is a newer version of the TI-84 (CE Python) and I wonder if it handles more like a TI-84, or like a TI-89. Are there any other (modern, and preferably rechargeable) calculators that I should consider?

So when I turn it on I will be able to start typing immediately without the delay of the TI-89? You've tried this calculator?

I hit the "ON" button and the screen lights up and it is responsive in less than 1s. I hit "ON" and immediately typed a number without waiting for it to light up and the number appeared exactly as I typed it.

I complain incessantly about devices that are laggy and I don't feel any lag with it.

Thank you. If you could compare it to the TI-89 lag I'd love to hear it. Regardless I really appreciate what you just took the time to write.

I'd recommend looking at a cheap TI-36X Pro. It's solar powered and responsive. It's not a graphing calculator, but it has the nice graphing-calculator features most people really need (movable cursor and multi-line display with scrollable history).
