This is quite possibly the coolest little thing I've ever seen. The possibilities span far beyond teaching kids to program on their own. While that purpose is awesome in its own right, the sheer number of configurations for this device alone are staggering, much less the possible applications for such technology. Granted, this type of tech is in all of our phones, but to be able to play with it in its most basic state without any sort of restriction is extraordinary. We're living in a post-PC era, and just like the tinker PCs of yesterday, we now have affordable embedded tech to play with while the rest of the world plays with their closed-system devices. This device has the power to not only bring electronics engineering and programming to a wider audience by supplying those interested with something so affordable, but it also has the power to teach GNU/Linux to a much larger crowd and will perhaps cause it to go mainstream. Regardless, I love this thing. Best $35 I ever spent. Heck, I'm using it right now!
Long Live the Pi!
