You don't. However, it does come with HTML5 and QuickTime installed.
Currently there is no flash player for the ipad. I believe that the new update will have it.
You need to jailbreak your ipad then download frash (flash) from cydia. I does not work all the time for me it didn't work but it did for others.
This is what the site said. "Adobe Flash Player is not supported for playback in a 64-bit browser. However, you can run Flash Player in a 32-bit browser running on a 64-bit operating system." Please...
