I like that you can upload your document into multiple different formats (MS Word/PPT etc). You are also able to see what each person has done before so if they made changes it is easy enough when replying whether or not its correct- no more fumbling about trying edit an old version! The only thing i dislike at all would be being unable too add other languages once downloaded - maybe because my account isn't set up right? It's great though really helpful with uploading files which could then go onto any device without worrying how many versions there will likely be by now!!
