I use Jelly, a tiny smartphone that fits the little keychain pocket of my running shortpants, I don't even feel it while running. They released a newer version of it, Jelly 2, if you're interested in small phones.
Kinda reminds me of my first gen Palm Pre. Loved that phone.
I have a dslr with two fixed (portrait and panorama) lenses, and night or day, every single shot is timeless. The quality won’t be outperformed by the next smartphone getting released next year. Of course, I can’t spontaneously shoot photos, need to decide when I want to actually shoot photos so I carry my camera.
Which is not a cons, even an advantage, if you’re truly looking for quality, not quantity.
