Claims you don't need a DSLR then produces a bunch of amateur photos as evidence.
I think computational approaches like the Lytro are the future. But right now, DSLR's still produce markedly better images thanks to faster lenses, larger sensors, shallow focus depths that create buttery soft backgrounds.
Some of those advantages, larger cameras will always have. At some point we'll probably ditch the anachronistic "reflex" part. The viewfinder gives you an inaccurate representation of the image anyway.
Smart phones are good enough for 98% of the photography that we do - vacation photos, drunk nights out with friends, that colourful homeless guy with neon tassels and a cowboy hat.
I can still easily tell a DSLR photo apart from a camera phone shot and it doesn't take pixel peeping either. Better dynamic range, sharpness, focus.
Still love my camera phone, in fact I don't even have a DSLR anymore. But I'm not going to pretend its anywhere near as good as a pro camera in pro hands.
Of course, we're geeks and love to expand our skills. One day we wake up and want to be a photographer dammit. So we buy a DSLR and take it to parties, dinner, public events. The big camera is a liability - you worry about dropping it or having it stolen. It also makes you look like a dork. Sometimes people give you flak for bringing a pro camera to no cameras allowed situations. When you do take pictures it feels like a ceremony. Of course, you have to nail the photo because you just spent 2500 on a camera. Every previously dismissible imperfection is now a bottleneck that prevents your camera and you, the ariste, from living up to their full potential. You need the external bounceable flash, the L series lenses, the filters and hoods.
