There's nothing to recommend this calculator over any other cheap calculator by TI, Sharp, etc. I bought it when my 15 year old HP48 died and this is just not a replacement.If you're out of high school, the idea of a graphics calculator is kind of silly given the accessability of spreadsheets, but as a statistician I found my HP48 useful for lots of quick calculations. The 30S has lost virutally everything I found useful (RPN, all the valuable probability distribution stuff) and has limited functionality in most other areas. What it has got is 3 different color face plates (what? do they think it's a cell phone?) and the virually useless ability to calculate means, standard deviations, and correlation coefficients (why would anyone waste time inputing a bunch of data into a calculator when they could save it in a spreadsheet file?).
