It’s no secret (to say the least) that the iPad doesn’t support Flash. This isn’t a bug; Apple did this on purpose. So if you have an iPad and surf to a web site that contains SWFs, you won’t see them.
As a web developer, you can work around this. Instead of serving your SWFs in the default player embedded by the Flash application or something like SWFobject (used by Dreamweaver), use Flowplayer. Flowplayer uses the QuickTime player that comes with the iPad and iPhone. There’s a free version that displays their logo, and there are logo-free licenses starting at $95. You can use any of them commercially. Get it at www.flowplayer.org.
