I spend several hours a week talking to our customers and interviewing the people who run mobile for large retailers, as well as mobile startup founders. The opinion I stated is definitely mine, and it's a logical conclusion based on the data gleaned from my interviews and informal/off the record conversations with people whose business it is to sell real products (hotel rooms, shoes, shirts) every single day via mobile apps.
People simply don't transact on Android - thats not an opinion. That's data. Happy to discuss more/share more off the record if it suits you, and if you know someone who is successfully selling products to Android customers, I'd love to talk to them because they know a secret that literally every ecommerce company in America is DYING to know.
As to the dozens of links to Hipmob - that's where we publish our interviews and it's the original source of our content. Believe me, if we could publish elsewhere, we would, but its the sort of content that only customers/potential customers of ours find interesting, and as such we make it available to them on our blog.
Hope that helps explain things.
