Exactly. Aside from the fact that I find the terminal is better in some respects, most users don't have to use it.
I also think its conditioning. Most students in schools get started with windows (somehow they think they're teaching computers, when its really just teaching windows), atleast that was the case with me, I had to discover linux on my own (I was getting sick of Vista), and ended up wiping my windows partition the first time
. But then it gradually unfolded, and I saw the light.
I think the more ppl start using linux in their homes and schools, the younger generation will also adopt it.
