I agree that regular people shouldn't touch the terminal, UX has come a long way to try and simplify the way we do things. Unfortunately there are things that people either don't understand and most likely don't care/want to understand (even with the simplest UI). It's up the tech savvy guys to change interface and dumb it down for folks. It's bad enough having to explain to someone where to do certain things in Windows 8; I don't want to have to explain to them why their wifi doesn't work on linux. Windows 8 is a huge pain, it's hard to understand when there is more than one way to change something. Then mixing what are essentially mobile apps with desktop apps just muddies the water. Uninstall in Windows sometimes doesn't even work. This is not to pick on Windows but it's usually what people have.
