Where cloud storage fails is when you just need to get access to one or two files, and your local application does not have any functionality for accessing files stored online. I find myself in this situation all the time with a few OpenOffice documents that are synced with a Dropbox account, but the Dropbox account itself is not synced with all the devices I use. Editing files in this siutation is a case of logging into Dropbox, downloading the file, making some changes, and uploading it again. It's a tedious process. This is where the Ooo2gd (which stands for OpenOffice.org 2 Google Docs) extension comes in handy.
