Well, I'm glad you found a workaround of sorts, but I still think something is amiss there. When I add a handful of text rows to my test file and shovel it on over to the iPad via USB, it takes even less time than it did for the initial install. It dawned on me that perhaps that was because the bulk of the file was those two images, so I replaced them with different images and repeated the experiment yet again. Still faster than the initial upload.

I don't have a satisfying explanation for what you are experiencing, I'm afraid.
