One of the things I've really missed (and more so my oldest son) is the ability to work with Lego Mindstorms with a kid friendly environemnt. The RoboLab program worked in clasic but was bugy and a pain to get just so. The programming env worked ok but getting a program uploaded to the RCX was always a pain. Well they finally updated to work with OSX. Rock and roll! Andrew (oldest son) is now reading the programming manual (instead of sleeping). Next up is to make him do the same thing in Java that he is doing with the RoboLab stuff.
If you are not familiar with it LeJos is the way to go for doing java, the Eclipse plugin works well too. Its been a while sence they have had a release but it works like a champ.
