I got an HP48G in high school for UIL[1] competitions at the direction of a math teacher, and once I got the hang of it, it's been hard to use anything else. The competitions were a mix of math and seeing how many problems you could go through in 30 mins using a calculator. Pretty fun once you get the hang of it, and the HP48G/RPN did give me more time on non-numerical problems. The IrDA is finicky, but the programming and builtin features are great. The feature set is a bit much for a high school student maybe, but I used it through all of college too. I probably played a bit more minesweeper on it than I should have. The HP prime and Droid48 apps are nice, but I just don't need calculators as much anymore.
