Hi,
Similarly surprised and disappointed that Win 11 is not compatible with my i7-6600u Surface Book, and I'm guessing that my wife's SurfacePro from about the same time is also going to be in the same boat.
Our Microsoft PCs represented significant outlays for us and were purchased in the belief that we were getting a high-end product which would provide many years of service.
They're both still in excellent condition and certainly not ready to be turned into useless landfill yet.
I hope MS reconsiders their position, making high-end MS PCs incompatible when they are still in good working order takes away any incentive to spend extra dollars for MS products.
Thanks.
