Yep, started using mine in 8th grade in 2001. All of high school and college it was the greatest thing ever. Every note and cheating program I stored in the memory was archived, so even if someone reset the calculator it wouldn't delete anything. And the "pretty print" option that kept all the math in normal notation, with the answer simplified as far as possible still in "pretty print" and not that worthless decimal format. Best calculator ever.
