Works!
First and perhaps most important: it really works. Openning and editing word files with Apples "Page" or other programs was always a problem. Files adited on the iPad, saved with these "competing" tools never looked the same.
Most important advantage: openning and editing files with comments and mark-ups. This functionality gave me a chance to say goodbye to my laptop and (still I am on the way almost everyday) saved some kilos from my bag.
Disadvantage? Still certain functionalities of word are unavailable. But I am patient.
