Well, look at this. If you've been desperate to know what your App Store experience would be like on the iPad, here's a chance to live the dream. Apparently these shots were discovered while the App Annie folks (an app tracking and analytics site) were "searching for clues" on the device and this "actual feed" was stumbled upon. While that's all very unclear, what isn't unclear is that Apple will be using the HD moniker to denote applications that have either been tweaked in a special iPad version, or have had their resolution upped so they wouldn't just be scaled standard apps. Additionally, we're seeing some applications that aren't even available on the iPhone right now, such as the $49.99 OmniGraffle, which we're assuming will be very close to its desktop counterpart -- a good sign that iPad apps are majorly upping the functionality. One more long shot after the break for your viewing pleasure.
Update: Looks like App Advice has even more screenshots for your viewing pleasure.
