Of course, but I was talking about the incentives of an average user, which I'm not sure care about security as much as we do.
Just to make what I'm saying more concrete: most people in my home town in Sicily think it's perfectly OK to bring their phones and laptops to some random guy owning a tech-assistance shop and tell him their Facebook/Email passwords straight away so he can reinstall stuff and save their login for them. Do you think they care about upgrading because of "improved security"? I'm not sure they even understand what a security issue is...
