Ipad 2 can run softwares and usb drives?

Using the iPad 2's 30-pin connector, Apple sells peripheral connectors that allow you to connect your iPad 2 to a projector and attach a USB key. The USB connector is limited to transfering only videos and pictures, however. Both are also about $30 a pop. Apple has an app called Keynote in the app store; its basically Apple's version of MS PowerPoint. I'm not sure if you can save Keynote documents as PowerPoint docs. The app costs $9.99. And for keyboards you can only either use Apple's Mac keyboard made specially for the iPad, or you get can a bluetooth keyboard (requires iOS 4 or later). A bluetooth mouse would probably not work since theres no mouse cursor in iOS. Hope this helps.
