For those of you unfamiliar with what these are, they are programmable Legos. The kit includes little servos/motors, and a very intuitive “programming” interface for your computer. Reviews are overwhelmingly positive, and they’re proven to develop interest in programming and logic in children.

He’s the right age for it (a bright nine-year-old, though the thing says it’s for 12 and above). He’s really enthusiastic about building things with Lego already, and has a zillion parts. I think it could be a good bonding experience for us to build things together.

“Cool!”, I thought. Except he already has an expensive Lego toy in the closet, and then I looked up the price: $250. Ouch.

Has anybody here tried these out? What do you think? Worth the cost?
