That's not true. Ipad apps are usually gratuitously more expensive and if you buy them, you won't be able to use the app on your iPhone and iPod too. For most apps I stick with the standard version. Mind you, I only use my iPad rarely, usually for distraction on plane journeys; not recharged more than once a month.
No, I'm saying that I personally have bought relatively few apps that are specific to the iPad, and where there was a choice between an iPad and an iPhone app, the difference was not often compelling enough to get me to both pay extra and forego access to the same app on other devices. The killer app category for the iPad in my experience is distractions and games, and they don't lose much being scaled up.
