Im not quite sure theyll fully replace cameras. I admit that its a huge hassle to switch between cell phone and camera, especially during family gatherings. Together they take up entirely too much space in ones pocket and its a pain switching. But the thing is that the phone doesnt take the best of pics. Maybe its because I have an Android phone but say you go out on a sunny day, you can take pics that rival Kittyladys. Excellent pics there BTW. But when it comes to someplace dark, like your own house but the corner where the light doesnt reach so well, even the flash cant fix that problem. If the subject happens to be moving, that photo is more than likely going to end up horrible. On a camera it may come out bad or you could get a nice blur effect, that wont happen on a phone. And dont even think about the video. Oh it works perfectly, even catches the subject moving, but once you move while youre filming it messes up and there is no going back. The whole thing is messed up from then on out, unless you stop it and start a new one. I prefer my camera, where I can move all I want, take all the pics I want and film all the video I want. I dont see phones getting that good anytime soon nor do I see them coming anywhere near the $1,000 cameras with the fancy lens that people use for artistic photos.
