ArsTechnica reports that Microsoft is mandating secure boot, but as one commenter puts it “it will go largely unnoticed because no one cares.” I fully agree with this statement. Most people are not technical people and will have no idea what secure boot is. On top of that, it is REQUIRED FOR ARM systems only. Most ARM processors, I bet, will be on tablets. Why would you or anyone else who gets a Win8 tablet feel the need to enable/disable secure boot? Linux? VirtualBox is great software. Use it someday.
