If you're on anything, google documents is excellent - and you don't have to back up, you always have your documents, they are available mobile, and best of all, collaboration. I'd never go back to an installed word processor. The net benefits (no pun intended) are just too compelling.

Are you referring to the same Apple Pages that hasn't been properly updated since 2009 (excepted for iCloud integration, yay!). Also, in my opinion, Pages is a usability nightmare (only opening the inspector makes me want to cry :D)

I am looking for something smart. That will have a distraction free editing, markdown support, pagination and all the good stuff. Some small git integration. So my girlfriend can do version control on her works. I really miss that.
