I'd rather see classes get Ardunio kits and learn about hardware, coding and design. This Makerbot announcement is a gimmick. 1 printer per class = 1 kid getting to print their design while the others get to watch. Repeat during the next day.

For the same cost as 1 Makerbot printer, you can get 30 Ardunio kits with 100's of components. http://tinyurl.com/lxlrsv4
