Christina Warren:

Ten years on, the least important part of the iPhone is the phone itself.

Make no mistake, cellular connectivity is a huge part of the device (if it wasn’t, the iPod touch would still be frequently updated), but the “phone” part of the iPhone is one of its least important apps, and the app that I would argue is least consequential to the device and platform’s success.

I can count on one hand the number of times I use the Phone app each month.
