I just installed it - I will be giving it a good test over the next week as I have a bunch of travelling to do for work. I will let you know. (I have been using the web app for the past several months so I don't imagine that I will see too much of a difference but I like the idea of just launching a simple app instead of logging into the web app) - Since most of my trips are already synced on my Outlook Calendar anyway I don't think I will be using that feature - But I will be testing it to see how it integrates.
