I also cart a "real" camera around with me when I go on vacation. My phone camera is pretty awesome for what it is, but nothing compares to a dedicated camera. Bokeh is important. Low-light performance is important. RAW capture is important. High burst rate is important (I'm often taking pictures of kids--my "real" cameras take 5-6 FPS in burst mode, all at full RAW resolution). Real optical zoom and stabilization is important. Being able to control ISO, aperture, and exposure time is important. Having a flash you can bounce off the ceiling is important (and no, a phone flash isn't NEARLY strong enough). Time to first shot is important (my camera can take a picture within about 600ms of turning it on in programmed-auto mode). I have RAW capture on my phone if I use the right app, and some control over exposure, but none of the other options. If I want to document something and I don't have a real camera handy, sure I'll pull out my phone. Android 5 gets the time between pulling the phone out of my pocket to first shot down to 7 seconds, which still isn't nearly fast enough. My old Canon 10D took 3 seconds to first shot, and I often missed shots as a result. When traveling I usually carry around a micro-four-thirds camera with a couple of lenses; very small, very fast, and great low-light performance (as well as all the other features listed above).
