I would argue collaboratively editing documents is by far the most common and interesting use case, followed by presentations. You seem to have an odd, complex workflow which is representative of 0.001% of the population. I'm glad Excel works for you. Microsoft does well with a number of complex oddball legacy workflows, full of VBA macros and what-not. Your style of working collaboratively isn't very collaborative. Google Docs does allow that (you can share with suggesting changes), but for the most part, there's a gap between getting feedback on a document, and working together on one. I find version control to be super-helpful too; it's not like I don't see the changes after someone makes them.
