I don't really get why everyone is talking about Flash and its relation to porn. If the the number of non-Flash playing devices grows, couldn't these porn sites just go to HTML5?(this applies to all other video sites, actually)
I'm pretty sure porn sites will adapt pretty fast. Nobody wants to be the last porn site not supported on the iPad.
Well, he could also be talking about no flash memory card slot. If you were to watch non-streaming porn on the device, I doubt that you would want it to be in the same place on the device as your regular movies (lest you hand the iPad to someone else that stumbles across them). You would probably want to have your porn on a memory card that you could remove when you are no longer using it.
Or in a locked "porn vault" on the device. Which there are already apps for.
