Because unless 7 year old Linux handles the same hardware better he didn’t prove anything more than 7 year old OSes have issues with new hardware, which is kind of a no brainer.
No the article is stating that Linux is easier than XP definitely but the truth is his testing didn’t prove that. He’s making a conclusionary statement based on uneven testing of unlike circumstances.
And actually he didn’t prove it doesn’t work. All he proved was that XPs generic network drivers had an issue with his particular network adapter and he needed to use the driver disk that came with the computer. BFD.
What he did was install the most commonly used version of Windows on generic hardware from a major box manufacturer. And it didn't work.
That's an indication of how Microsoft does things.
