Very good point.
Actually, my thinking was not far from yours and so, just before reading your post, I bought OmniFocus on the Omni Store.
I do enjoy supporting developpers as every one does but my monthly income is not so high so questions like upgrade fees are key for me to get a software or not.
That said, OmniFocus seems to help me a lot after the extended trial so I am now betting that the ROI will be very good ! (That is mainly a way for me to make my brain think I have to buy software... I have to admit that)

So I leave this thread to others now as we'll see how the MAS goes in the future. And so I am off to the poll...
