David Chartier, in response to Jason Snell and John Gruber’s opinion of 3D Touch:

I’m surprised at these perspectives on what seems to be a by-the-book Apple feature introduction. Not only are 3D Touch, peek, and pop quite useful (perhaps after some new muscle memory), they have the same introduction and adoption pattern as other recent, significant Apple hardware innovations. […]

I wager 3D Touch will simply take time for many of us, and maybe a couple more ads as well. It will also get a couple more chances in the spotlight as Apple rolls it (and any improvements) out to the rest of iOS at major product launches.
