The thing to remember about legOS is that pretty much anything you can
do in C (gcc, egcs) in 32k of RAM, you can do with legOS.
I believe that both legOS and NQC have definite places in the RCX programming
universe. I happen to have been using gcc for about 12 years and have used
it to program miniboards, so I am naturally more comfortable with legOS.
legOS is going to become more easy to set up and use while NQC is going
to become more powerful and flexible. This is an exciting time. :-)
