If Trevor followed any economic sense or logic he wouldn't be in the Amiga market at all.
The fact that he decided to ignore sense and spend his money the way he wanted to - rather than the way many would deem sensible - is something I and many other AmigaOS 4 users are very grateful to him for.
Basic economics says that it's impossible to make much money in the Amiga market these days. Supply can be made but the demand isn't there. Therefore supply has to be lessened. Less supply means higher prices - economies of scale. Higher prices then means less demand. Getting the balance right is very tricky and I think Trevor did it well with the X1000.
Trevor aimed for the high end of the Amiga market, leaving Acube with the low end, which makes complete sense. That meant using high end components like the PA6T despite the cost, on the grounds that the Amiga users really wanting as fast a machine as possible would have deep enough pockets, and they did.
Commodore were in a BIG market but Trevor isn't - hardly anyone wants a platform with very little software, even at a low price. In the 80s, small companies existed to make big games and programs, which helped push demand. Today people expect programs made with budgets in tens if millions of dollars or more. Not practical on a tiny OS.
Whatever we do, we will never be able to take advantage of economies of scale like Commodore did, it's just impossible. Comparing Commodore to A-Eon is pointless unless you also compare the meerkat that A-Eon and Commodore are in.
Trevor knows full well about economics, but he chose to spend his money the way he wanted to and benefited hundreds of others in the process, and for that I applaud him.
