Windows 8 will be a trainwreck. Too many changes for most users. The issue is windows 9 (whatever that will look like).
And everyone in Microsoft land will be so delighted that Windows 9 sucks just a bit less than Windows 8, that they won't mind the fact that the "Windows 9 Certified" program will prohibit OEM's from allowing the user to disable UEFI Secure Boot.
That way, when Windows 10 comes along, you won't have a choice.
The one day you'd sell your soul for something, souls are a glut.
