A bit unrelated, but are people actually getting anything out of personal task managers and ToDo lists? Supposedly they are to help me do the right thing at the right time and not worry too much. In the past, I would do fine without a todo manager and primarily used my mail inbox and text files to keep track of things. As the number of responsibilities and hard deadlines grew over the years, it simply became impossible to keep track of everything. Moreover, I would realize that I forgot something urgent when at home, etc. I decided that it's not doable anymore, tried some todo managers and settled on OmniFocus. Now I just add tasks with the appropriate due dates or defer dates when necessary and forget about them. It gives peace of mind and I rarely miss deadlines ;). The integration with iCal is great - the Forecast gives a nice overview of what I should definitely do on a day. (On-topic: I did once try TaskWarrior and the vim plugin, but I like OF's integration, syncing support and ease of use.)
