I've liked lejos on the RCX, I played with that at "school". Now I'm the happy owner of an NXT with the cool new features and was hoping to put Java programs on it, like on the RCX. I also ordered the book "Maximum Lego NXT: Building Robots with Java Brains" from Amazon, but it's delayed until end of April. As the "book description" on Amazon mentions lejos, I'm wondering how the lejos progress and the release date of that book are related..

And just how things are going. Or should I start learning something else, like NXC? Suggestions?
Regards,
A java and lejos fan
