I bought a new SLR body probably every 5 years for the last 40. My newest smartphones are so good I've given up. Yes if you want crisp incredible detail, or if its your wedding you need an SLR, but no other reason.
I sync my camera photos to my Photos library along side phone pictures and whenever I’m flipping through to share something with a friend, they always notice and comment, “You took those on your phone!?” The difference is still huge.
