The developer has chosen a route whereby potential customers have to chose if they want this application based only on a video tour, there is no trial option. Based soley on the very poor video, I can only agree with previous comments/reviews.
TaskMagic appears to offer very basic capabilities, I'd go so far to say that I would jot tasks down in Tex Edit rather than purchase this.
To the Developer: I'd strongly recommend you re-do the video, please pan out!
Perhaps you might want to re-consider the price and providie a trial.
You are in a very competetive market and right now TaskMagic may be detrimental to your other applications and your credibility as a developer.
