Sure it would have been nice if the Amy would be mnuch cheaper then the MicroA1, but I guess that is just not possible with so small productionbatches. To bring down the prices conciderably you have to increase the numbers by 100 times and there aren`t that much potential buyers anymore.
Anyway even at the same price as the MicroA1 the Amy is in advantage:
USB 2.0
GBit Ethernet
Sil onboard
no GFX onboard (yes, I count that as a pro, as on the MicroA1 the GFX is practically nonupgradeable. Though you can waste the only PCI-slot it has with a GFX-card, if there isn`t allready a Sil sitting in there)
The only con would be the soldered in CPU, but with no CPU-Module available for the MicroA1 now (and probably in the future) it really doesn`t make a difference.
Troika sure didn`t start to design the board to underbid the MicroA1 price but to deliver an OS4 compatible board at all, as there was doubt for a long time if we would ever see something from Eytech again.
