I am about to do a clean install of Mavericks and I am thinking of only installing iWork. I do have Office 2011, but every month there's a critical update. I wonder if I could get by with just iWork. I don't collaborate with anyone using Office, but I do need to be able to read Office documents when they are sent to me. When I create a document I send as a pdf. Have I thought of all the scenarios where I might need Office? Btw, I do have Office 2011, I just don't want to install, if not necessary.
