Yes audio interface would be nice, but I was thinking of just the ability of charging one's phone or tablet while they were listening to it. Just a convenience. One could include a Raspberry Pi or Aurdino for the clock, calendar, and tuner too if those things are important.

I don't have a tablet, and my phone only needs charging about once a week. I don't find it inconvenient to walk to another room to charge it - the exercise is probably good for me.

FWIW I carry a tablet around when I do boring repetitive work such as drilling PCBs, winding transformers, Tolexing cabinets, painting or punching chassis and myriad other boring but necessary tasks, and since internal speaker output is mosquito buzz quality and level, I also carry a small powered cabinet with it.
Sometimes I use my phone as a "read aloud" player.
Your phone´s battery may very well last 1 week ... in standby/listening mode that is, but continuously ON screen devours batteries.
I added a USB charger to my powered monitor, to keep tablet or phone toppled all the time.

My point being: I can personally vouch for at least *one* person using an USB charger embedded in an amplifier power supply
Design/make/service musical stuff in Buenos Aires, Argentina, since 1969.
