Cameras in phones have pretty much killed off the idea of a separate "point and shoot" camera for some time now, and yes, phone cameras can do some absolutely amazing stuff, especially combined with things like in-camera HDR, editing on the phone, instant cloud backup, and ability to share your photos pretty much instantly anywhere you have a data signal. That's pretty neat stuff, and as they say "the camera you use is the one that you have with you". So they are a great blending of two devices in one, and very useful.
That said, it's not all pixel count. A DLSR is going to give you full creative control, plus a full choice of optics optimized for whatever you might be doing, from macro work taking pictures of tiny subjects, to astrophotography, and everything in between. You can also do things with shutter speed, aperture, zoom, etc that you just can't get out of a phone.
I have both. The phone gets a lot of use because it's pretty darn good for what I use it for, and very convenient. The DLSR is hauled out for when the serious picture taking happens.
