Re: "most people are now computer literate"
My experience of the current teen generation (I teach them every day) is that they are computer literate as long as it involved FB, Instacrap, twatter and the like. If it is anything out of their social media needs they a haven't a clue and are more than likely to give up, call the tech a piece of crap and walk away FBing their experience. This is not really their fault, the opportunities for learning about tech have diminished over the years due to the prevalent attitude that "the kids know the tech coz they use it all the time", consequently even the simplest applications based courses have been canned. It really is time to call bollocks on that. Currently the only students who have a clue are less than 5% of the school population that I work in, if you look at the teachers it's about the same if not less.
