A new use for margins

While I still read books on my way to work, I recently started reading online articles and blog posts using my phone as well. This morning, while I was reading a column on Alertbox on iPhone, I noticed with pleasure a small detail: the left and right margins of the page have more than a merely aesthetic purpose. As anyone who ever used an iPhone will certainly know, you usually slide your thumb along one side of the screen to scroll the page you’re reading.
