In a gesture of trying to find the features of the new iPad from Apple, we watched a video and it you can really do a lot with your hands and fingers.
You can slide two-finger across the screen to drop grenades. You more than drag and drop but drag and and tap tag to make a group of items to move. Demos show ways to edit photos and set elements.
You have two and three finger swirls that do different functions. It will definitely be a hit with designer-types.
By the way, we realized a whole market for the iPad, Baby Boomers who can't read the small type on the iPhone screen who still read books! Then instead of putting on glasses the Boomer can just increase the font size, no more embarrassing heavy large print editions of books.
