I've experienced that very limitation from people when it comes to online document editing and maintenance. However, my experience with how those kinds of people use Sharepoint is still compatible with Googledocs: create a document with Word or Excel, then upload it into shared storage where the document goes to die because they never edit or use the document again. Google docs supports this workflow, uploading a Microsoft Office document which gets converted. Now that I think about it, can you upload a document to replace the one that is currently there in GD? I'll have to test that. That would negate the I-can-only-learn-one-thing-and-that-one-thing-was-microsoft-office mentality.
