NQC's primary advantage over LegOS is that it's easier to install and operate.
LegOS requires a lot more "stuff" that people just wanting to play with the RCX
probably wouldn't care that much about. LegOS's primary advantage, on the other
hand, is that it gives you a full C programming language to work with, so you can
have your own struct types, more variables, and as a native code compiler, it gives
you full access to the RCX's capabilities. NQC programs can only operate the RCX
in the way that LEGO's operating system which is uploaded to the RCX as "firmware"
allows. It is this "firmware" that LegOS replaces. An RCX running LegOS programs
won't be able to run normal Mindstorms programs until the the normal "firmware"
code has been re-uploaded back into the RCX.
To the best of my knowledge LegOS, shares none of the weaknesses that NQC has. The
only disadvantage to LegOS that I can see is that it's not particularly simple. It
makes me think of the idea of using a firehose to put out a small kitchen fire
instead of using a handheld fire extinguisher. NQC, following this analogy, would
amount to something less than a fire extinguisher, in my opinion... probably the
equivalent of a single bucket of water.
