It doesn't matter as a core of the OS is being decided by POLITICS, oh and FYI but that PC World article? Its bullshit, its changed a grand total of TWICE in 20 years, from VXD to WDM, from WDM to DF, and you can still use WDM even on Windows 8. I have used XP drivers in Windows 7, that is 14 years of driver support, show me a video of you using a 7 year old driver without playing the make and break game and we'll talk.
If the core of your OS is decided not on its merits but by politics? Then your OS is doomed to become a punchline. BTW the zealots have been making the same excuses for so long that you can break down more than 90% of posts on any Linux article into just the same TMRepo memes, why? Because like Dems and Reps all that matters now is the politics, NOT the OS.
