I don't think the problem is the number of features really but maintaining the simplicity or ability to access the features you need. For any given product there are probably a core set of features that everyone wants and beyond that each additional feature pleases some other slice of the customer group but before you add that extra feature you should probably consider what that might cost you in terms of maintaining the simplicity of access and ease of use of your core features.
