Right, but my thesis is that the upgrade-train model of software revenue is faltering. I think Sparrow is evidence of this (what you say about Sublime could apply as easily to Sparrow.) I think it is a large problem, and we are seeing the manifestations of it now. Time will tell, but I'm sure not gonna work on one-time charge software, nor would I recommend it to anyone. I'll work on free open source stuff, financed by work on whatever recurring models I can figure out.
