It looks like a good choice for equipping your own child with an engaging platform for physical computing and robotics, but at in its price range of "hundreds of dollars" there are many good choices. It is at the "nice present for a privileged child" price point. We could really use more choices that are at the $20 - $30 level where it becomes an easier decision to equip whole classrooms with one for every student in the class.

It's a trade-off between features/usability and price. I'm sure this one has its niche. It's much cheaper than a Lego Mindstorms kit, and probably easier for kids to use since they have the android and ipad interfaces.

But there is an ultra low cost (~$10) robot kit in the works (trade-off of course being less features/usability), but it's not available yet: https://sites.google.com/site/affordableeducationrobot/home
