Hi, I've recently changed over to using Outlook 2010 for managing my task lists, and just noticed that the GTD guide recommends only using tasks, not flagged emails for NAs, although Outlook can do both and there are other setups on the internet that use both. Any thoughts on reasons why and which is better? One pro for me is that Outlook tasks sync to my phone much better and I can see them in the same app I use for my home tasks, but flagged emails don't come across. However it's faster to just flag an email and assign a category and I can also do this from my iPhone, whereas to setup tasks with the email in it I need to be on the laptop. Would be interested to hear what works for others.
