I have Office for Mac, and when the 2010 version arrives, I will not install Outlook. For GTD functions, Omnifocus is head and shoulders better than Outlook, particularly if one wants to see NA lists by Context and then by Project, and would like easy sync to other devices, and easy backup in the clouds. I have considerable experience with Outlook, and I submit there is no comparison.

Look at the big picture.....
