Well let's broaden this, there is no concept of files on the iPhone, and yes, you DO need them. Example: try attaching an excel sheet you received from a friend to another email. Example: the powerful Android "share" mechanism --the sole reason I have several iPads but switched to Android for real work (ie on my phone). Share is not limited to a bunch of "friend-aware" apps, but every app can register themselves as a "handler" for particular data objects (files), e.g. "picture" "pdf document" etc, and when you hit "share" all of these are shown in a list. No more circuitous nonsense where you have to open a file in goodreader or save it to dropbox first, so you can access it with another app, which speeds up things tremendously. I think it's pretty safe to say that moving data from one app to the next is something everyone needs.
