I loved the RCX, grew up on it and learned basic programming from Robolab, which I like better than that new Mindstorms for the NXT, you had to think through all the "steps" in Robolab where it does the work for you in mindstorms... so it either does twice as much as you want or none at all...
The NXT does have more memory, and is much more organized as it's own computer entity. And yes, not going straight was the RCX's one big downfall...
