From the reviews I've read it seems the only way to view your own documents (videos, PDF's, etc.) is to either mail them to your own internet based email address, or import them into iTunes. That would suck. I'd like to just copy them over to the flash drive via USB or WiFi. Is that possible?
I don't believe so... at least it's not on the iPhone. It's really pretty easy to import pictures, and videos through iTunes. PDF's though, probably not... unless you convert it to a jpeg in photoshop and treat it as an image.
