It's wrong. Nokia supports frals in making fMMS good for Maemo 5 :-) I like MMS, I want MMS - and I think that fMMS might well achieve a "good enough" functionality soon. Conversations integration is not that important, it will be enough if the connection switching happens automatically. And this seems to be on the roadmap. (did you know that you can already send photos with fMMS directly from the photo app using the Share function?)
