I like the concept, but it seems... expensive.<p>Maybe I'm just spoiled by the Raspberry Pi, but I'm having trouble swallowing a $60 machine (and that's without any of the other gizmos that attach to it) when there are examples of products in the same niche that come out to a bit more than half that. Does the fancy low-power radio really cost that much?<p>On the other hand, I don't think the Arduino or the various other prototyping/microcontroller boards like this are any less-ridiculously priced, so maybe this is actually competitive and sane relatively-speaking. It still seems strange, however.<p>On the third hand, I suppose I could just download the schematics, source everything out, and figure out how to build it by hand. I have a feeling it would end up cheaper, even without being able to take advantage of bulk rates on the components.
