I'm wondering if this would work better as a Google Apps survey. In particular, there's a big difference between an app that takes one guy an afternoon to write and an app with man-years of development time. To get some insight on that, I've thrown together something here:
Only got one response. My comment didn't get enough upvotes for enough people to see it. Considering reposting as a new submission, but I suspect one app survey on the front page is enough for this week.

Please look at it and make suggestions about what I am missing. I will of course publish all the data.
