The most amazing thing here is that they are offering the option to purchase optimized Tessels with different modules baked into the main board, and you can get as few as 10-99 of these optimized Tessels for as little as $35 each.

This has huge potential if you want to create your own Tessel powered device and resell it. I love that the Tessel people are making hardware as easy to work with as software.

A combination of 3D printing and optimized Tessel really opens the door to all sorts of interesting, cheap, low volume, internet connected hardware.
