It's definitely a tool if you want "a" data point "really fast". I won't argue against that. However, I would use it for "just" that and nothing more. I wouldn't use it to drive the entire decision.
Per your point of disagreement, and depending entirely on the type of app, I stand by my point. You're anchoring the disagreement "quality". A down and dirty "test the waters" app is a lot less expensive than a "quality" app (ignoring apps that can't really have a down and dirty, like complex video games or something).
I would agree, that on average, a "quality" app would take longer then a down and dirty "test the water" app. However, so long as you can get a down and dirty out the door so easily, we will see crap in the app stores.
