and uses it until it goes to hell.
maybe a reason so few OEMs ship computers with GNU/Linux preinstalled is that, is they ship GNU/Linux the computers won't get malware etc, so the people will wait longer before they buy a new computer, and them being greedy bastards don't want that.
That's only part of the equation. Another part is support. Let's say Compaq began selling laptops with Fedora Core pre-installed (forgetting the fact that Microsoft would punish them for this). If something were to go wrong, the Fedora Group/RHL takes no responsibility. Contrast that to Microsoft, who takes responsibility for their OEM installations. Ignore the fact that Microsoft support doesn't ever go beyond "reinstall". At least they have an obligation to the purchaser and to the vendor for support (even if it is only the illusion of support). The only way to get this from Linux is to install an enterprise Linux, which costs a shitload of money, making it a bad idea for consumer consumption.All of this may mean shit to you or me, but it is something that Compaq and Microsoft and the Fedora Group take very seriously. That's one reason you don't see too many Linux boxes at consumer retailers.
with a bit of effort and a bit of money I bet any OEM could make it work.
Hey, that's good news. With more support maybe more people will switch or have less of a problem switching. The article only mentions support for Linux servers not desktops, but surely if you can support servers you can support desktops too.
Giving them telephone support costs a lot of money and makes the supporters want to kill themselves.
