Exactly. The counter to that (as discussed in this post) is that you can just search for documents based on keywords, etc. which can definitely work well in many cases – but I don't believe it is (or has to be) an either-or. Searching is not infallible either - at least not until search becomes semantic and truly smart, lest I misremember crucial keywords, substituting a synonym (or any of a number of examples). It's been my experience that organization becomes essential when tasks become complex. This goes beyond computers. This is the case with human systems or physical objects. I think the same goes here. Mobile devices have largely been about consumption or simple creation, with simple workflows. To me, it's an open question of whether or not their current interaction and organizational scheme can hold up as content creation gets more complex.
