How many meaningful competing products does Xbox have? You can count with one hand. Same goes for Azure. Now think about how much competition Evernote has. There are tons in each category. Heck I can even build my own note app in an hour using Dropbox, iCloud or any other cloud storage providers (which by the way are much more stable than Evernote) Lastly I don&#x27;t know what you mean by CRM and SQL (since they&#x27;re a category and not exactly a product) but basically all these enterprise products from MOS were successful because they already owned a successful platform--Windows. Evernote doesn&#x27;t have any successful platform and its product had too much competition with little competitive advantage.
