I've been playing with GTD applications for some time now. I agree with another person's review about Thinking Rock - although the interface is cumbersome and it's easy for me to get lost in too long a list I have never suffered data loss in that program.

I recently copied over items from Omni Outliner Pro 3 to OmniFocus and have tried to use it as my main task program. I have kept up with the changing editions almost daily posted on the Omni website and am shocked that in the past 2 or 3 days I have a (most current) program that keeps losing my data!

Yep, a task copied and pasted from Outliner Pro, OR typed in. In both cases and trying 3 times I inputed data, clicked on a different category and when I came back to the recently inputed category all of my new information was gone - each and every time!

Wow. I am beginning to think some brilliant soul should invent a way to export our task lists out of 1 buggy GTD program and import them into another more desirable program.

How terrible iGTD 2 is only for Leopard. It looks like the guy finally developed a functional interface.

What about Midnight Inbox and Frictionless? Has anyone reviewed these products re: ease of use and reliability?
