I'm specifically speaking of casual desktop/laptop users, I used the word computer to generalize. It's not evangelism in the slightest. I'm not saying you are wrong about a lot of casual users of computers in the broader sense using phones. My point is specifically talking about casual desktop/laptop users. 

 Those are a minority of laptop / desktop users nowadays. Now you get why x86 linux is unpopular? 

 Again not my point. I'm not speaking of popularity. Even if they are a minority there are still casual laptop/computer users and that's what I'm talking about.
