I think m0nastic is right. I use some of the apps you mention, but also use Rdio and RunKeeper on a daily basis. Those both materially affect the enjoyment of my phone.
You certainly have a point, most apps are downloaded then never used. But I think everyone's "few apps" are different with lots of overlap in the apps you mention.
