The iPad (and its kins iPod Touch and iPhone) won't need Flash. The sites that currently have Flash will make specific Apps of their sites tailored for the iPad's screen, just like the way Apps have been made for the iPod Touch and iPhone. Apple gets to count more Apps in the AppStore and developers get to tout their special iPad-designed user experience for their site. The iPod Touch and iPhone don't currently have the full web, but do users care if they have "an App for that"?
