So I just updated my iWork apps and found the new iDisk integration to be pretty sweet. You can “copy from” and “copy to” iDisk, which opens a popover window allowing you to browse your iDisk.
Conversely, you can “Open In” from within iDisk itself into iWork apps.
Is this our file system?
With this and built in printing coming in iOS 4.2, I may finally retire Goodreader (my de facto file system) and replace it with iDisk. I may also retire Airsharing (which I use only for printing).
I’d still prefer to have something that feels a little more robustly integrated into the device itself. But perhaps that is coming…
EDIT: NOPE!! Just dug a little bit more into the iDisk app and it lacks even rudimentary file management tools. At the very least I need to be able to create folders, search for files, and cut/copy/paste docs from place to place within iDisk. i.e. The stuff you can do with Goodreader!!!
