No, it's almost impossible to break your Newton while testing a piece of
software. The worst that can happend is that you would be force to do a hard
reset, but that's all.
If you don't have any programming experience, it might be hard. Even if you have
programming experience, it's hard, at the beginning, because NewtonScript is
like nothing that is out there. After a while, you become more comfortable and
things go a little bit better. I've put an HTML version of a programming book
for the Newton. I could dig the URL if you want to give it a shot.
