Wow, easy there champ, I think you may need to take in some light music to calm you down lol. Personally I think there is a better chance that the person that can't use a modern phone is the simpleton but, I find being respectful and leaving childish insults out of my posts allows conversion to run more smoothly...
I use my phone to run room correction(XT32 App), adjust PEQ, control my subs, steam lossless music to my systems, control my AVR, use a SPL meter app, and a number of other sound related tasks including researching system upgrades. That doesn't account for the thousands of other uses other then sending and receiving calls. Other then REW, I haven't touched a computer or tablet in probably two years as my phone is the most comfortable and smoothest running option while chilling in the couch and/or out and about. YMMV of course but, as you can see there is plenty of audio value, if you will, in opening and closing apps...
