the fact that everything is easier once you get the hang of it.) is that it makes it so that no one ever wants to borrow your calculator.

I can't tell you how many times people would beg me to use it and I'd try to explain that it was tricky and I'd show them how to use it. One of two things would happen:

1. They'd be insulted and just take it, try to use it for 10 seconds, then hand it back without making eye contact.

2. Let me explain how to use it, try for 2 seconds, then hand it back and say "it's not worth it."

In fact, My Calc teacher give me a 48GX to use "as a backup" because he was too ingrained in TI's system. He also said he wished he'd never switched to teaching TI, but it was in all the books and was just easier to not do a whole separate overhead (yup I'm that old) for the HP.
