iPad app with sync and same sort of keyboard shortcuts would be great (and would pay for handsomely). Clearly a lot of effort and intelligence went into TaskMator, but for me it somehow didn't translate the simplicity of TP to a touchscreen interaction.
I use TaskPaper throughout the day, every day. I've tried at least a dozen task-management apps and TaskPaper is the only one that I keep coming back to. It strikes just the right balance between simplicity and customization. I could go on and on, but just know that I, for one, think your pride in the project is justified ten times over!
