Secure Boot is probably one of the lamest systems in place. It's clearly a move by Microsoft to try to further their monopoly, and stifle migration to other systems. That's why you should only buy laptops from https://www.system76.com/, or http://zareason.com/, or http://www.emperorlinux.com/. You wouldn't have to deal with Microsoft's BS, and you would get a pretty kickass computer in the process.
