There's this interesting phenomenon on the Internet where people have a hard time seeing beyond their way of doing things. It often goes one step further, and you see people telling other people that they're using their devices the wrong way. This same discussion happened in the Evernote forums, too, when a segment of that community asked that the app be password-protected.

Personally, this feature isn't a big deal to me, but I can see how someone might want/need it. I'm assuming the "don't share your iOS device" comment was a joke, but, if not, it's pretty myopic to tell someone that his use of his iPad is "wrong," because he shares the device with a family member. I know plenty of people who share their iPads in the family.

One of the Android ROMs has an interesting features where you can restrict access on an app by app basis. Perhaps overkill, but helpful in some ways.
