Not sure what the adoption rate will be. From my reading, about 90 percent of the hardware today will not run Win11 (has to be fairly current generation CPUs - last few years). So my guess is that it will not be widely adopted as it will require purchasing new hardware.

I for one do not want to purchase a new system. My current system works very well on Win10. The feature list of Win11 does not have any features that I would "have to have". So for me right now it is a no-go.
