It's a shame, I almost feel like calculators are obsolete in the era of the cell phone.

I really liked my Ti-83+ back in the day. TI-83+ BASIC was my first programming language ever... now I know like 10. But there was something beautiful about the fact you could compile it right on the calculator, and code-on-the-go. I used to write TI-83+ apps when I was done with homework and bored in class. I made a stock market investing game, and a horse racing betting game... haha good times
