How it works and what it does and what it's made of are very different things (cite: Zen And The Art Of Motorcycle Maintenance) and once the novelty of how it works has worn off (yes, kudos, BTW) what is left is a mildly interesting device. The SDK and ecosystem are also mildly interesting, but the cute factor will wear off quickly and it's probably go the way of Neil Young's Pono.
I feel it's pricy novelty product. And even with SDK, I wonder will there be new games in couple years? I don't think they will actually sell enough to justify development time...
