Good advice. But of course, many people do not have the necessary
skills (or time, or friends with the necessary skills and time) to build
their own PCs. Which is why they purchase pre-built machines.
I've known *many* nontechnical users who bought their machines from the
corner dealer thinking they had something ultra-high-powered and bleeding
edge, when it was two-year-old hardware and cheap no-name parts. Look
through the WGA gripes in this group and you'll notice an inordinate
number of them come from people who bought their computers from corner
computer stores and ended up with a pirated Windows.
Nontechnical people are at least experienced enough to know they are
better off dealing with respected retailers and known brand names. Fierce
competition for shelf space and the retailer's aversion to angry customers
and large numbers of returns tends to keep things honest, and I've never
yet seen a one-off computer beat the sale price of an equivalent
mass-produced/mass-marketed system.
Also, more than half of the computers sold in the US now are laptops.
There aren't very many corner computer stores that can build custom
laptops and I wouldn't buy one there anyway because local retail stores
already have them dirt-cheap. However they'd be even cheaper if I didn't
have to pay for a bundled copy of Windows than I don't need or want.
By the way, I don't believe Microsoft HAS any such thing as an
"exclusionary OEM agreement" any more. That was gotten rid of by the
courts when Microsoft was found guilty of monopolistic behavior, if I'm
not mistaken.
Microsoft has been known to build secrecy clauses into their OEM
agreements. In their case against Microsoft, BeOS claimed that secret OEM
agreements like the ones that came to light during the antitrust trial are
what shut down their own access to the market. So how can anyone ever know
whether Microsoft is still doing secret agreements?
What one can do is take a black-box approach, look at the millions of
copies of Windows XP Full being sold versus the total lack of bare PC's
in those same retail stores and via the large respected Internet dealers,
consider Microsoft's history of secret agreements to maintain just this
situation in the past, and deduce that they're still doing it.
OEM producers are now free to install any OS they want. And many do.
In fact, many OEMs will install any OS YOU want on your machine, or none
at all, for that matter.
Maybe if you mail-order or are lucky enough to have one of their outlets
in your city. However you cannot walk into the usual places where most
consumers commonly buy their computers and pick up an Intel-architecture
machine minus Windows.
