There's huge difference between easy access costing nothing extra and "knowing what you are doing" and 259GBP / year. For you, the setup you have chosen suits probably very well but please understand that it's not for everybody. I bet there are many people who would enjoy offline features and do not have the money and know-how for Outlook with hosted Exchange. Relevant modern interoperability is a very loose concept. There are many types of sharing. Consider that with Google docs you can share a document for example as a web page for free. Other factors such as already using one Google product such as Gmail and Google Contacts and the synergy of using other Google products. But yes, I agree with you partially that this problem is solved. Just not for everybody.
