Incogneato - i'm looking into that software further. It's complicated lol. There are two versions of NXT-G. ONe for the retail market and one for the schools. The one for the retail market has 4 robots you build and program. the one for the school market actually has a tutorial which takes you step by step through all the blocks and simple programming. You can buy the School NXT-G for $20 which I did.

OK, now there is a software package for schools which is $255. I just noticed yesterday that a very similar looking package is now being sold for the homeschool market and it's $40 or something. I'm in the process of trying to find out how this pkg differs from that sold ot school. It seems to be only a single user license w/ no other differences. I want to know how that software differs from the tutorial in NXT-G which ships w/ the school kits. If you give me a day, I'll be happy to research this and report back. I don't want you invest money on something you don't need.
