yes, we read same texts but I would never say: "we must remember that ST was designed in rush to not loose market when Atari lost Amiga technology."
1) Jack Tramiel never "lost Amiga technology"
2) how to lost market to Amiga, when Amiga was different league with almost double price
on other hand, Mac was already out and press compare Atari ST to Mac, not to Amiga: famous "Jackintosh".
beside, Amiga Inc. show prototype of future Amiga to Jack earlier, but he dismiss it in the same way as Steve Jobs dismiss it - to much chips, to complicated. It passed 3 years until Commodore manage to cut down cost of Amiga 1000 with Amiga 500 model. As I said: Amiga would not fit in Jacks "Rock Bottom Price" plans of new computer.
