I'll share some numbers: I've got three utilities in the Mac App Store, two currently free: WindowFlow[1] & Window Keys[2], and one paid: Optimal Layout[3]. Firstly, from what I've seen, only the US store really matters for paid apps. I've seen very low numbers move Optimal Layout to close to the top of the category: e.g 5 sales in Canada placed it at #5 in the top paid utilities. In the US Optimal Layout hit #4 in the top paid utilities and #40 top paid overall with 82 units sold in a day. For the free apps, WindowFlow was the best performer getting the most downloads in Japan & France (for some reason) hitting the number 1 spot in both store with about 700 downloads a day. Neither of these translated into many sales for Optimal Layout, but it was just great to have lots of people trying out the apps. So overall it's not a big market yet, being a part of bundle like MacUpdate or MacHeist delivers access to a much bigger market (40,000+ in 2 weeks) but it's relatively steady and only going to get bigger. I'll revive my blog soon and post a more detailed analysis of how I see it playing out.
