I think a lot of these comments are missing the point. There is a huge difference between a mouse and a finger and you cannot just abstract this difference away by pretending that hover is only used for tooltips. Flash programmers from the very beginning embraced the platform because it allowed dynamic and flowing interaction with the movement of the mouse pointer. I can think of dozens of very common Flash techniques that will never work with a finger without being re-writen. * Combo boxes that only expose the drop handle of hover. * Controls (video) that only appear when you move the pointer * Camera controls where the mouse motion is used to anchor view. * Animated buttons, flyouts etc. As an example I did a google search for "flash examples" which led me to http://ziggystudio.com/v1/main.html http://ziggystudio.com/v1/main.html This app has an "AUDIO" link in the upper right that scrolls out on mouse over to expose the actual controls. This app simply will not work in a finger environment and would have to be re-written. I would argue virtually 100% of the flash applications written will have broken functionality in a click+drag only environment. Most of these apps will "work" but in a massively degraded state. Many of them will simply be incapable of being used. You cannot gracefully degrade to a click/drag system from a hover/click/drag system. They are too different. Flash was developed to maximize the mouse paradigm. It will never work well with a finger interface.
