Actually, the price policies are very real. I can't get into the details of it but I can assure you that if a company can save 1 million by saving 10 cents on a part, they will do it. If the result reduces the ability for a small percentage of its customers to not be able to do something, then so be it. Most kids can barely program 4 sensors, let alone 127 of them.
Always keep this in mind when you are faced with limitations of the NXT platform: "You are not the target audience." LEGO loves its AFOLs and fosters this community but when the NXT was designed, the AFOLs were not what drove the design process. AFOLs do amazing things with the NXT and the people at LEGO are very glad they do, but, again, we were never intended as the main selling market. Things turned out a bit differently, of course, with an estimated 50% of all NXTs owned by adults.
20/20 hindsight and all that.
