I disagree, it's useful to be able to click a document link and quickly preview it in your browser. At work, I have native apps for Word, Excel, PowerPoint, etc. and I still find myself using the browser version for quickly responding to a comment left in a document.
It's also useful to be able to quickly send someone a link to collaborate on the document without needing them to install anything. Installing a separate app may not be possible for aging parents, people using shared computers (e.g., library or school computer), or organizations with restricted IT systems.
