That's why mainframes and the PC XT, as long as they're good enough and carry the IBM label, will dominate the business market. And they are good enough; Apple can't depend on being the only one with a reliable quality product in the market anymore. Being the best tool for employees isn't going to impress purchasing managers.
Apple's products have always appealed to the people that are going to use them. Corporate purchasing doesn't work that way. The people making the decision about what to buy aren't the people that will use the tools.
Apple would be better off setting its sights lower, on academia and consumers. Maybe someday they'll figure that out. I, for one, am excited about the new "Macintosh;" that may be the future of personal computing.
