My article is in no way focused on "how to" attract normals. This is simply an opinion piece on why you should focus on Normals rather than techies and early adopters. I just saw this post on Hacker News and I did not select the title. :)
In addition to your rationales, which I largely agree with, I'm sort of partial to "People who are normal pay money for things, even things not made by Apple, even in prices above $1.99."
