I'm thinking about buying an iPad, but am seriously concerned about the file management on it. (who isn't) Anyways, I have some very large files that I need to be able to read and edit on the iPad to make it worth a purchase. How does one get say a 350mb keynote file onto an iPad? Obviously it's too big to email. I think PDF's should be ok using GoodReader or some other similar app, but what about things like Pages? Does all the file management have to take place by emailing it to yourself over and over? Is there a 'documents' tab in iTunes? If so, can you provide a screenshot? I know this has been discussed at some length, but I haven't seen a post that directly answers this question. Thanks!!
