Have you tried browsed the Internet for extended periods of time on an iPhone? It's painful. The mobile experience still sucks for 90% of the web, bandwidth is limited and slow, and don't even imagine having all your standard tabs open. Mobile web is still very much broken.

I pointed it out earlier but like the author also don't have home Internet. It's pretty easy to avoid grabbing the iPhone and opening up safari for anything more than reading a few blog posts.
