I think this will be the most monetarily successful social network yet. While Facebook has a huge mindshare I don't think they are very good at turning that mindshare into money in their own coffers.

Apple is really good at daring to ask for money for their services. While other companies often rely on ads or even more nebulous ways of making money, Apple just asks their users to pay money.

I really like this model of paying for what I get. I means that I am the customer, and not the product.
