Over the past ~1,5 years I have used my iPad in the same way. I still appreciate it greatly for what it is, but over time it has become incredibly cluttered.
* Once you switch your preferred text editor a couple of times file management becomes a mess. You probably didn't copy over and delete everything immediately but you moved _some_ files over to try it out. Now you have different versions of everything, all of which you're afraid to delete. If you hitch a ride on the iOS text editor hype train every so often you'll have three/four of these red flag apps stashed in a folder somewhere within a year.
* If you use more than one app on the same text file there will be numerous copies of it in different apps.
* Some apps support 'open in place', meaning they don't copy the file you're editing to the app's sandbox. But I don't know which apps support this and they all use different terminology to tell you on use (if they tell you at all). In addition these files or file pointers may or may not be differentiated in the app's local file system and may or may not be there when you reopen the app.
* Each app has its own, separate tagging and/or folder solution.
* Some apps have a genuinely clever way to solve a problem that should be solved on the OS-level. These solutions make no difference to me; only one app supports them, and using them is mildly intuitive so I never get beyond using them once or twice.
And on it goes. I have found the best use for my iPad is to treat it as a stateless machine. My passwords, bookmarks and apps are on it and that's what I'll use. Then I move the files elsewhere and forget about the internal storage. In that capacity it's the best device I've ever owned.
Well, I've settled down on the iOS text editor hype train, which helps a lot with this, admittedly. :) I tend to write in Ulysses or Scrivener, both of which sync between all my devices (the former transparently, the latter...not, but that's not an iOS issue, as near as I can tell). The other alternative is just a designated Dropbox folder that iOS apps are told to point to; from a user standpoint this reduces a lot of these issues.
In theory, apps don't have to have the problem you mentioned, as there's an "open file in place" API for them to use (and even an "open directory in place" API) which avoids all the document shuffling. Unfortunately, a lot of apps don't seem to really support it particularly well. And I'd still prefer the apparently crazy, radical idea of having a shared Documents folder.
