Time magazine recently announced its list of 50 Best iPhone Apps 2011 divided into the following categories: games, on the go, lifestyle, music & photography, entertainment, and social. I see that Instapaper is on the list. That was one I wished I had downloaded to my iPad before taking my recent flight to San Francisco for Macworld. It lets you capture web content for offline viewing. Overall, this is an excellent selection of must-have apps.
