Another backer here. Backed the sd card pledge so have to see what board I'll use (I have Raspberry Pi lying around but might upgrade it to the pcduino). I hope to use astrobox to use in the classroom because all my pupils will be working on ipads next year. I use the Doodle3D box now, at my school and the fablab where I volunteer, which is great for first encounter with 3d printing and creative work but hope to use the astrobox for more "serious" work. Could be great if It would work directly from an app like 123d design or Maker Empire.
