Video and screengrabs in this post: a first hands-on experience of the free Marvel Comics app for iPad, produced with Comixology (who produced a popular iPhone app). Word is that more than 500 titles will be available through the application at time of launch on Saturday. The pre-launch copy of the application I'm testing shows many titles offered at $1.99, and a number of selections also available for free. All the Marvel classics are here: Avengers, X-Men, Hulk, Spider Man, IronMan, Captain America, and a number of newer titles. User interface details of note: the ability to finger-flip through, page by page; scrollable bar of thumbs for all pages at the bottom of the page view, so you can skip ahead easily; double-click to zoom into an individual frame and finger-flip forward to advance frame by frame instead of page by page.
