I can think of nothing better than to be able to create a Pages document on my MacBook, save it to my Dropbox folder, then on my iPad open it up, continue working on it, close it, and then be able to open again on my MacBook and see all the changes I made on my iPad.
Of course this isn't quite possible. You can open files in the Pages app from the Dropbox app, but you can't save them back there.
So then, today, I heard of a service called DropDav. It acts as a WebDav interface for your Dropbox account, and lets you open and save documents directly to and from Dropbox within the Pages app itself. The only problem is that it costs $5 per month, which is actually quite a lot.
I've also heard of CloudDav, which claims to do the same for a one time fee of $5, but I've heard it's slow and I'm guessing its unreliable? I'm not sure, I can't find anything about it. If you buy a cloud file management app from the app store for $6, you can get CloudDav included.
So is WebDav the only way to do this, or have other members here found another? And DropDav, is it worth it? Honestly I could see myself using it every day, but $5 a month seems like a lot of money just for this one function, no matter how useful.
