One of the main value propositions of web apps such as google docs is that your data is stored in the cloud and accessible to you AND others on any machine that has a modern web browser. The value I currently get out of local Microsoft Excel over Google Spreadsheets is waning as the quality of such web applications increase. I think the mac app store is going to be great for single functionality novelty apps, but any serious product, especially those that require a lot of collaboration will stay on and continue to move to the web.
