To be fair, it would slightly reduce the xhance of the user really messing it up. If they remove the screen too we might finally have a user-proof computer. No more "I've forgotten my password", no more "I put the internet in the trash can and now I can't find it", and no more "I didn't do anything (they absolutely did) and now it doesn't work, this must be your fault. (As the local 'techie' it's not my fault, but it probably is my problem). Fix it!! (sigh...)"
