I was really hoping you'd come to your collective senses and put file share and wss document access back in with SP1. The feature was used more than I think you believed it was, especially for smaller companies. Obviously, removing it was nothing more than a business ploy to 'urge' people into SharePoint 2010 w/ web apps or even better - sign up for 360.
To this day, the 2010 documentation still says the functionality is there. At the very least you could fix that. Perhaps you could offer up some realistic suggestions for replacing this functionality? In the long run wouldn't it just be easier for you to put this back in?
Finally, how do you expect us, your partners, to sell customers on functionality built into your products only to have you turn around in 3 years and remove it? I'll tell you one thing, features like these might not be important enough for you to keep developing, but to our customers they are.
So, who are you developing products for - your customers, or yourselves?
