If you're a Canon shooter, their free software does just about everything PM can do; and just as fast. However, you have to ask yourself if you need ratings or cropping to follow over to LR. That's about the only thing that you can't do. If you don't need that, Canon's utilities get the job done just fine. I don't know too many people that do any actual editing in PM. Thus, I don't see the need for the extra spending, personally.
