No, Intel did not say that but they did implied that other OS on ARM will give a disappointing experience.
“In Salvator’s view, ARM may be just fine for such consumer experiences as those provided by Apple’s iPhone or any one of a squillion Android smartphones, but at low power-consumption levels it can’t have the oomph to provide what customers expect when it comes to a Windows-based machine.”
I think M$ and partners will compensate for that by developing more complex ARMed devices but they will then be more expensive and power-hungry. Of course, GNU/Linux on ARM already gives a great experience.
With the biggest “partner” of Wintel criticizing the developments of the mother-ship, how long can the Wintel monopoly last? Intel will find that GNU/Linux runs well on Intel as on ARM and Intel will find it profitable to be partner of GNU/Linux. It’s all good.
