Google Drive: Hands-On Winner - The BrainYard - InformationWeek

Excerpt from a Google Docs-centric view of Google Drive

"Tuesday's introduction of Google Drive is more a revamp of Google Docs than it is a brand new service. Essentially, Google is rebranding Google Docs to Google Drive, and modifying its user interface to suit a bunch of new features.
Docs already lets users create documents, spreadsheets, and other files. Those files could be edited, shared, downloaded, uploaded, and so on. None of that has changed, only now Docs, er, Drive users have a minimum of 5 GB of storage of which to make use. There are a few key differences, however, that dramatically improve the usefulness of the whole shebang."
