One of my children's favorites among the stories I frequently tell them is how different technology was back in the day, at least in my opinion. Digital cameras were extremely uncommon, and computers were the size of a file cabinet.
The dependable graphing calculator is still in use. the original Texas Instruments, which includes our TI-84 CE. Today's models are sleeker and have color screens, which my old model lacked, but I don't remember them being as button-heavy.
