An anecdote perhaps but Microsoft's Office online proposition is virtually unusable in the "outlook.com" form at least. I haven't tried 365 yet but I imagine the codebase is the same. Even in its native browser (IE) it falls over with stupid rendering errors: http://i.imgur.com/kLDQ0f3.png http://i.imgur.com/kLDQ0f3.png And it can destroy an 8 core Xeon with a 5000 row 2 column sheet... No thanks. Edit: also I'm not walking into another ecosystem. After they shot windows live domains a few days ago which I and a number of people I know were using, we're out.
