Re: someone who designed builds for corporate laptops/desktops
When the Help Desk can't assume they can start an instruction with "Click on the Start Button" because a user might not know what the Start button is, lockdown is the only choice.
We offer some choices at the desk I work on now. I don't want to tell you the number of dead silences I get when I ask "Which browser are you using? IE, Firefox, or Chrome?" Or worse, the number of people who confidently answer "Firefox" and then when you visit their desk or remote it, they are running the Big Blue e, version 8* (which you know doesn't support that Google Apps feature and would have made troubleshooting the problem so much simpler).
*yes I know, IE 10 is out, 11 will be soon. We consider it a victory we were able to get them off IE6. And there are troubling but legitimate business reasons to keep them on 8.
