Apple published on its web site the list of most popular sites which completely optimized their resources for the iPad. That means no flash on these sites, they use such web standards as HTML5, CSS3 and JavaScript instead of it.
The list of key sites is as follows:
• CNN
• Reuters
• Vimeo
• Time
• Major League Baseball
• The White House
• Virgin America
• Sports Illustrated
• Flickr
• People Magazine
• TED
As assures the Cupertino company this is just the beginning!
The Daily Show and the Colbert Report also have great pages.
