This is a matter of taste. It works better for me. I have used phones, Sony's specifically, that do sport a dedicated button. I never used them because I'm not used to the location of the button I use once in a while. The power button however I use multiple times an hour so I can put the phone into camera mode and take a photo with my eyes closed.
