Not really true. Until Linux is used by at least 10% of home computers
are verified Linux computers, vendors will likely not think of Linux as
something that is used by non computer geeks. Many already think Linux
has come of age.

I think only new converts wonder if Linux has come of age. Remember that
tablets and smart phones running Linux are the standard and not the OS
fighting for a spot in a market. Microsoft is that company. Microsoft is
also the company fighting to regain lost market in the server market.
The only way they may make ground in the future is the stand that Intel
has made. For intels stand I would hope that Intel looses market share
as well.
