First of all, the firmware does not prevent you to use other OS. Only one function is locked to Windows and it seems Microsoft is open to allowing others to boot with it [sidenote]. Secondly, every single iPhone/iPad is locked to boot iOS; most of the phones with Android are locked as well. (And obviously Windows phones are locked too). And by locked I mean locked, not few clicks away from using the device as you wish (as is the case with notebooks and desktop computers). How come it's not rendered illegal? Sidenote: I agree with the fact that Microsoft shouldn't be the one deciding who gets the key and who doesn't. My opinion on this is that if everyone can't agree on one impartial organization then hardware manufacturers should be the one deciding it. Obviously it would be best if users could add their own keys.
