I'm saying that people who want to run Linux as their primary desktop are not a market of interest to hardware manufacturer's.

Indeed, I am going so far as to suggest that it may be a market in which hardware manufacturer's are explicitly disinterested due to the potential support costs.

Furthermore, the wide spread expectation that a Linux machine should be less expensive than one with Windows due to the elimination of license fees might make the market even more unattractive to manufacturers.

Supporting Linux is expensive to the point that Red Hat has made a business out of it.
