even though Apple just make PCs these days, that doesn't stop them selling them, and indeed, having people get quite enthusiastic over them. These days, people want modern PC hardware, and companies differentiate themselves in other aspects, such as design, cases, services.
So I think there's certainly plenty to be said for Commodore's approach
Apple remains in the market because they just don't "sell pc's".. they control the whole architecture with the os and components. Apple is not in the same ballpark as Hewlette Packard or Compaq that deal in cheap hardware using other people's technology.. which CUSA falls into.
