It is a long story, but the jist of it is the supply of some of the A1 components dried up.
Really? You mean that they would have continued to produce the hardware with defect chipset if they hadn't run out of some of the chips? Tell me it ain't so...
Well, I guess it makes sense. They did sell 3 different "AmigaONE" motherboards to people, all defective the same way (more or less). 4th wouldn't have made a difference.
Seriously now, my understanding is that they finally figured out that the northbridge they used (Articia) was hopelessly flawed. Instead of investing tons of money to new design with new northbridge (which wouldn't have sold more than couple of hundred units) they decided to pull the plug. Good move financially.
