I think that’s why closed box things like iPads are doing so well right now. You aren’t the administrator of your iPad. You have some administrator rights, but not all of them. Same with gaming consoles which have been around a good long while.
I want to be the administrator of my own computer, but I think for most people that really isn’t what is useful to them. It’s too large a skill set for a device that was supposed to be making their lives easier. I’m probably the only person in my office who actually uses the fact that we have general purpose computing at our fingertips. I think having that much power and not knowing how to use it is a big part of why some people are so afraid of computers.
