Following on from the post about moving off of Xtra for email it seems a good time to talk about Gmail. It is a whole lot more than just email, calendar, tasks and contacts (which it does exceptionally well with). Google Apps provide Word, Excel and Powerpoint type applications all in the browser (so you don't have to install anything). It also is a great storage option (Google Drive) for personal information but should not be used official or TSA related information.
If you haven't heard about it or tried it before then I would suggest you head to Google.com and signup for an account then start exploring. It can simplify your life and make information portable (so you don't have to go to your computer to access that document) and shareable (yes you can collaborate and work on Google documents (spreadsheets and presentations) simultaneously with someone else!
