Pari is mostly for the unixes. Pari is a great shell calculator :-| and contains many basic number-theory operations. I have looked at some implementations of its functions and they seem quite up to date, yet somewhat slow. This must be the result of a slow multi-precision package so be warned. Otherwise it contains most of what you would want for general number theory problems and calculations. I personally perfer Mathematica 4.1 and pari as my two most utilized calculators.
