Sted, you're missing the point. Completely. I don't need Apple to choose my apps for me.
Since you asked, the ones from my "useless apps" pages that come to mind are notes, contacts, calendar, tips, nike, podcasts, health, stocks, maps, reminders, passbook, newsstand, books, passbook, clock, and safari. Now, the latest one: watch. Is there anyone that can tell me why Apple would bundle an app that no one can use?
I'm not saying that no one should use these apps. I don't use them, and I don't want them taking up space on my phone. If they're truly useful, users would download them from the app store.
In response to your question "if you are using so few, why did you purchase a smartphone?" I'm NOT using "so few" apps. I'm using so few bundled undeletable apps. Ones that I find useful are irrelevant. Instead of listing them, I'll propose a counter question: What's the point of calling it an "iPhone" if the user has so little liberty to set it up as he chooses? Maybe it should be called an "Apple smart phone"
