I don't disagree with what you say about the core experience and the danger of generalising from personal experience but there have been 14 billion app downloads. That's a lot for something which a lot of people seem to be suggesting is either irrelevant or niche. I think what you say may have been true in the past but I do think moving forward apps are playing an increasing role, even if it is just three or four for…
I suspect a lot of those 14 billion downloads are games. If my experience is at all typical then most users go through an initial frenzy of downloading "productivity" apps only to eventually erase or ignore most of them. Apple likes to tout its $2 billion in app sales but consider that's what one really big blockbuster film might make worldwide. Proportionally it's a tiny market.
If you wish to say that $2 billion is irrelevant then we'll disagree on that (and it might be worth noting that in terms of box office receipts only one movie - Avatar - has ever made that in any case) but to put the scale in terms that relate to the mobile download market as opposed to some random unrelated market, sometime likely late this year app downloads will surpass iTunes music downloads (and to put that in context iTunes is the largest seller of music in the USA and has over 80% of the legal US music download market).
That 14 billion apps equates to over 60 apps for every iOS device sold (http://www.asymco.com/2011/01/16/more-than-60-apps-have-been...). If the suggestion that most people aren't really using third party apps is true then a small but significant number of people must be downloading hundreds and hundreds of apps each. While I'm sure that some people are doing that, I'm not convinced that enough are doing it to allow for a significant installed based doing nothing at all. Personally I consider myself a prolific downloader and I don't have two hundred apps.
One point of clarification which is worth noting - this figure is new app downloads, not updates. If I download Twitter then three updates that counts as one, not four.
For what anecdotal evidence is worth (not much) I don't know a single iPhone or iPod touch user who doesn't download and use third party apps and that includes people inside and outside of IT ranging in age from 10 to 40.
