Mathematica 9!

So I finally upgraded my desktop's version of Mathematica to version 9.0 (though my laptop's version is still 8...), and I noticed that the biggest difference is that Mathematica 9 actually lets you attach legends to any plot you have. This is huge! It's also interesting how Mathematica 9 will sometimes suggest commands for you to use while you're typing them, as sometimes they're really off...
