Brendan Tobolaski, on his reluctant decision to stick with OmniFocus:
I like a system that allows me to organize tasks by project but, also can make a list of available tasks regardless of the project that they are in. I don’t feel like there is a system that combines both of those and so I must stick with OmniFocus.
Between the OmniFocus 2 stability issues and design / functionality regression, the extremely dated Mac app, and just general complexity, I have seriously considered switching. I came to the same conclusion as Brendan — there just isn't a better solution available today.
Gabe and Phillip have done a great job exploring TaskPaper and plain text based systems. Maybe they'll convince me one day, but for now, OmniFocus is a habit that I just can't quit.
