Flipboard is probably the most pleasant-to-use news magazine app. You get to flick between a wide selection of sources on all general interest topics, and many of them offer reformatted content especially for Flipboard, which makes an easy read. Flipboard is well-integrated with Facebook, Twitter, LinkedIn, Tumblr, and Instagram, so all of your friends' updates will be displayed in a sleek magazine format. And Google Reader integration means you can invite all your RSS feeds to the reading party. Flipboard, though, doesn't allow fine-tuning of article selection by vetoing subtopics or sources, as Zite and Editions do.
Flipboard for iPhone and iPad is free to download.
