I dont know about that. Wal-Mart offers pc's with Xandros (and, they are dirt cheap). They started offering pc's with Lindows/ Linspire back in 2002, too.
I think alternatives to Windows are there if people seek them. People just know Windows and like what they know. You tell Joe Average that you use Xandros (or Fedora, SuSE, Ubuntu, etc.) and they have no clue what you are talking about, much less how to use it.
I think Linux just needs better marketing to gain bigger exposure. Of course, that costs big $$, which most Linux compainies dont have.
