One time a fellow TA needed to borrow a calculator (this was before smartphones). A gal offered him one from her purse, one of those the size of a credit card with tiny little buttons. I had a big thing on my desk that looked like an old adding machine (especially by comparison). "Ted doesn't want to JUST push tiny buttons and do some math," I said. "He wants a CALCULATOR-SHAPED EXPERIENCE." I showed mine to Ted...

...He took it. "...Yes," said Ted. "Yes, I do."
