Wasting time making games on my TI84 in the back of middle school geometry taught me how to program.

How is the battery life? Rechargeable sure is nice, but the older models lasted forever on 4 AAAs (at least my TI-83). That's one aspect that would justify the low processing power for today's standards for portable computing devices.

Loved it in university and still use it on my phone:

Do these graphing calculators still use Derive (tm)? pity, there is no pc version anymore

I personally think this is stupid (e.g., the new interface for selecting functions). The interface on original 84 was better. I still have mine from 15 years ago. I still use it.

They clearly haven't met a classroom of high school kids. Then again... I didn't have access to the internet in my pocket when I was in high school so....

I have no idea how on earth a scientific calculator costs almost as much as a cheap android phone. Do they use oled and snapdragon soc these days? Back in my school days a 20$ Casio seems more than enough.

You will have to pry my TI-89 from my cold dead hands. I wish they still made it

There is something impressive about a product line that can remain culturally relevant for this long, even if part of that durability comes from a very protected niche.

Great memories writing games in TI-BASIC on sheets of loose-leaf paper to later transcribe manually into my TI-84+.
