During the WWDC 2010 Keynote today, Steve Jobs announced new features for Apple's iBooks app, including the much-in-demand ability to take notes, the ability to tap and and bookmarks, and support for the PDF format. Jobs also announced that, while it's only been on the market for 8 weeks, iBooks already accounts for 22% of the eBook market. They also repeated that it would soon be available for the iPhone.
The iBooks app is now available as a free download for iPhone, so you can read your favorite books anywhere. On iPhone 4, the high-resolution Retina display renders every page beautifully. Vibrant colors, rich illustrations, and crisp, sharp text make reading a pleasure. Turn pages by tapping the right or left side of the screen or by dragging the page corner (just like a real book). Jump to a different part of the book by visiting the table of contents and tapping a chapter. When you’re finished reading, iBooks bookmarks where you left off. It syncs with iPad, too, so the story you started on your iPhone can be finished on your iPad.
