	There is a case for open source design so that the cost of an Atmega2560 equivalent drops down. Note that GHz processors are $40 - [https://www.amazon.com/CPU-Processors-25-50-Internal-Components/s?rh=n%3A229189%2Cp_36%3A1253504011]. There is no reason for a MHz processor like the Atmega2560 to be so expensive.		There is a case for open source design so that the cost of an Atmega2560 equivalent drops down.

There is no reason for a MHz processor like the Atmega2560 to be about 50x more expensive for the computing power they provide.

	At $10 or $11 - the Mega chip is expensive, reportedly 50% more than the comparable pic24f. Why? Good old capitalism.

	At such cost, the case for DIY production is minimal. However, if the chip can be reused and recycled, there is a strong case for Design-for-Disassembly ~~savings~~.		At such cost, the case for DIY production of Mega boards is minimal. However, if the chip can be reused and recycled, there is a strong case for Design-for-Disassembly. With such a chip, however, the reuse part is difficult.
