Have I ever claimed that Linux is ready for general home use? I'll be the first to say that it sucks for almost all home users. But if you are in the enterprise, a standard install, after making basic user accounts, is generally more locked-down than a Windows install.
You don't know SQUAT about what OEMs are allowed to do with Windows today.
I do know they apparently follow Microsoft's example in how to configure Windows. First you want the users to make up for Microsoft's shortcomings, now you want to lay that on the OEMs?
No, do yourself a favor and don't extrapolate -- because extrapolation wouldn't be an accurate reflection of what happens in retail software markets. Software has a very short shelf life. It will only provide sales within the first 6 months. After that, sales turn into a trickle.
That figure was from before retail sales of XP even hit their high, still being second to a years-old OS. It would be extremely illogical to assume that these sales dropped to nothing immediately after this article, and therefore sales were not able to reach the millions of copies sold that I claimed.
Admit it, there are millions of retail copies of XP out there, all configured by Microsoft, all approximately the same as the OEM configs. I have one of these retail installs, an upgrade for that machine that started as a 486/66.
