Flipboard is an elegant and intuitive aggregation app for the news services and social sites you follow. It pulls in articles from traditional publications and a mix of content (e.g., friends' comments and photos) from social services like Facebook and Twitter, and presents it all in an easy-to-ready magazine format. You effortlessly "flip" through the pages with a swipe of the finger. The latest version is optimized for the Retina display, meaning that images are sharper and more saturated, and the typography is easier to read. My personal take: Flipboard looks glorious on the new iPad. Even better, it's still free.
