Yes! Even closing the windows of programs that users no longer need is hard.

It's easy to develop a disconnect with the level that average users operate at when understanding computers deeply is part of the job. I've definitely developed it myself to some extent, but I have occasional moments where my perspective is getting grounded again.

It's a while since I've used Windows but I seem to remember it giving a choice of sleep, logout, switch session etc. I could totally see someone wanting a single button for it.

Ah yes, this task fails hard at the xkcd.com/627/ tactic of "Find a menu item or button that looks related to what you want to do..."

What do I want to do? "turn off my computer" What button do I press? "start"
