Consistent with the data presented in that post:

-I download lots of one-time-use apps. They're useful, and I won't use a phone without them, and then uninstall them in a week (eg, city specific apps when traveling)

- I download lots of special use apps that contribute few app-hours most of the time, but are super critical when I need them (hiking apps when hiking, service-specific references when I'm working in the relevant department, etc)

-I download games (lots of them), play with them for a while, and then uninstall for a new game. Yeah, most are gone in a week or a month, but the ongoing process is valuable to me.

(Edit addendum:

-I have apps I use quasi-frequently and that contribute very few app-hours of interaction, but are still valuable. Eg, the couple minutes a day I use a task list, the five minutes a week I use FreshDirect, etc.)

And then, yes, there are a handful of core apps that get most of my usage (outlook, kindle, Netflix, messages, safari).

This is entirely consistent with those stats, and still places enormous value on the app ecosystem.
