Dropbox? Google docs? Icloud? Help!

[BananaGio]

I have just become the owner of a shiny new Ipad and one of the main reasons for getting it was to be able to work on the go. I am trying to figure out how to work it by googling etc etc but am becoming very confused re the best way of accessing my documents and sharing them while working on my Ipad. So far I have got the Quickoffice app and have got Dropbox on my Ipad and PC. I have got as far as being able to access my documents via dropbox on my Ipad and can see I can amend them using Quickoffice but how do I then put it back into Dropbox so it syncs with my PC? Is dropbox the best way or should I be using something else?
Thanks

Hi

I've only used dropbox between a PC and a laptop but, after editing, you just re-save the doc to dropbox. It is then accessible in the newly saved format from any computer you are on.

it is me not understanding the Ipad I think that is the issue.I cant see an option on it to save back to dropbox, only to Quickoffice. And I cant see any way of transferring from Quickoffice to dropbox.
