I have been using MS Outlook 2003 for years as central part of my GTD system.
Lately, I have grown apprehensive about the crashability of Outlook. I am also not comfortable with the .pst file as I feel that if it crashes I won't necessarily be able to get it back.
I have used Outlook 2003 only because I felt that it was best for syncing with windows smartphone.
Has anyone here switched to a different software set with smoother operation and less concern?
