I have been using Mind Manager for a couple of years and recently upgraded to x5 Pro. (I really did not need to upgrade) I love Mind Manager and it is a perfect tool with the GTD methodology. I love the ability to add notes to the topics and include the relationships between topics. Mind Manager is worth working with to gain some proficiency. I tried to use the Pocket PC version but that did not work too well for me. I love nothing more during my weekly review to do this using Mind Manager and retaining the Maps for later reference. Many of my maps are works in progress such as my personal goals, marketing and business plans etc. I have also used the import tool with Outlook tasks but for some reason that messed up my GTD add in software. I would love to get some best practices from other Mind Manager users out there.
