Then again, since the majority of Linux user build their own desktop, I really see this not applying for it's a feature on the motherboard, not the OS. I can see the top-tier manufactures (Asus, Gigabyte, MSI, etc) allowing this feature to be changed, save on OEM boards where the majority of people buying OEM machines just use what is installed anyway.
I don't want secure boot in my build which I implemented as a dual boot system. Thus, I don't think I will upgrade to M$ W8 Pro. However, I may upgrade my Toshiba laptop can't use "secure boot' according to W8 upgrade assistance. M$ W8 seems to suck more than I originally thought.
This is awesome. They're finally bringing true security into the PC world. I know many of you don't truly understand the issue, but this is a significant step in the direction of good security for Microsoft and their business platform.
I know about this a few months ago and I'm waiting for it to be released.
