Bell & Howell Apple II update

What do you mean here, Ben? The PC didn't use a TV for output, and the MAC didn't use TV for output. The Amiga could, I suppose, use TV output, but it could do it at resolution much better than 640x200, and had a full range of colors at a time when the MAC and PC didn't.

First of all, within any market segment, investment in improved technology increases market share. That doesn't apply over different market segments, however. DEC, for example, stayed with "old" technology, charging WAY more than "new" technology prices for it for years. They typically lagged two generations behind in technology, yet exceeded costs of "leading edge" systems by a couple of orders of magnitude. Just compare the cost and features of the PC/AT clones sold in, say, '87-88 with a similarly equipped microVAX-II. The PC/AT would typically cost about $800 bucks, while a similarly equipped uVaxII cost nearly $100K, partly for the stuff the PC/AT had, and partly for what you had to add in order to have the stuff the PC/AT had. Inside a year, the power cost alone exceeded the PC/AT, yet folks LOVED the microVax and hated the PC/AT clone, that ran half-again as fast. If that DEC gear hadn't been so expensive, nobody would have bought it for sale to their government clients, since there would have been more profit in the PC/AT route.
