I suspect what will happen with porn in the iPad is what happened to porn in the iPhone: big video porn sites like xvideos.com and tnaflix.com will have a mostly pay site when the iPad is detected (that's what happens for the iPhone) and will be free for all the rest.<p>Their reasoning is probably that iPhone/iPad users are more likely to pay for the service, as they already do with songs, videos, and applications: this is one of the first results of this new closed world Apple is orchestrating for us, other companies will start to follow.<p>But... I'm starting to hope that the iPad will not be a success, as with iPhone the tech guys were mostly happy with it, as the constraints in the iPhone (let apart the approval process madness) are more or less acceptable for a phone. Instead power users mostly think at the iPad as a too limited device, as it is "almost" a computer but is limited in too many ways. Maybe if power users will not get an iPad this will have an effect in the whole market, as past successful apple product started to be popular among geeks first.
