Sounds like fun. And thanks for introducing me to yet another dev platform, on top of the Arduino, Propstick, Mercury, Nexys2, MSP430 Launchpad, and two Raspberry Pis I already have. :)
I'm thinking I should build something interesting with all those first, before buying more.
It is, however, really nice to see these inexpensive and highly useful platforms taking off in a big way. Pretty soon, instead of specifying individual parts for new products, we'll be specifying a platform plus whatever extra parts are needed.
