This was a cool story and, I don't mean to let the wind out of your
sails, but you must remember two things:

1.  Most people don't build PCs.

2.  Most people don't install windows.

They get windows pre-installed on their computers, direct from the
manufacturer.

And that IS easier than installing Linux (or windows).

Ease of install comparisons really aren't relevant to most computer
users.
