@anonymous, if it's my PC, I want to make sure it hasn't been tampered with (by anyone other than me). It's as simple as that. If you think secure boot is a problem then you probably leave your front door open at night and wouldn't mind if unwanted guests wandered in and messed with your stuff. To suggest that Linux and Mac OS don't have these issues is either a) naïve, or b) an enticement to others to use those other OS platforms until they become popular enough that they are interesting malware targets. Either way, the problem is not unique to Windows. I'll say it again--I want secure boot because I want to be in control of my machine.
