I've installed Dropbox (the 2GB freebie trial at this time), and it's working like a charm, in terms of getting a file from the mac to the dropbox, then picking it up with iPad, and loading it into iWork on the iPad. Problem is, once I make changes on the iPad, how do I get it from numbers BACK to the Mac. It seems to me that I can't, at least not through dropbox. I can export it from Numbers, and then synch with iTunes. I am sure I could also e-mail it (assuming it's not too large). But then I'm left with several copies: One original on the mac One in the cloud (on the dropbox server) One in my dropbox app on my ipad One in Numbers on my ipda One exported back out in iTunes One in finder (since I don't really want to store docs in the iTunes library -- at least I think I don't) Obviously, I can manually delete the leftovers, but I was just wondering if I'm missing something. Is there someway, after working on the doc in numbers, to send it back through dropbox, and manage the version control better.
