Haha you've obviously never worked in a big company or done any significant IT work with the public. I've got news for you, the average user is pretty much that person. In fact most people don't have his patience. There's a reason Mac devices are becoming so successful and it's not just the Apple catchet. Just looking up your favorite game on PC forums can be infuriating at times because the forums are filled with people like that who need support or don't understand something.
Well the genesis of this thread was a guy advocating command lines over GUIs. I don't think the average user would fare better with a CLI. I don't have a problem with someone saying a CLI is more powerful and efficient than a GUI but was just riffing on the idea of someone capable with a CLI "flailing" with a mouse.
