content: Overall a great tool and I have confidence that it will get to be a 5 star product as Microsoft iterates on it with certain kinks especially in the messaging section getting worked out. Some reviewers commented that it seemed too cluttered but I dont find the UI to be problematic it just takes a tiny bit longer to use than some of the Google products out there. But for that small cost you get a powerful app with a diversity of functions especially as it enables mobile editing of files.
