I haven't really looked into HandyBoard, since I found it to complicated
compared to the RCX. 20 year old tech works fine on the Space Shuttle and
other NASA projects BTW.
JCX seems nice, but $500 for a replacement is getting a bit steep for the
market, IMO. Ideally, a replacement for the RCX would not involve a huge up
front investment of cash to get started - that's why a modular system that
lets you add components would be ideal. Using up the 32K RAM you have? Get
another 32K module, add it in, and start using it. With a more enclosed and
sealed solution, you are limited in upgrade path.
