"I hate it because "do everything" devices will never outperform at a given task a device that was designed to do that specific thing and do it well."

Well, in the next ten years, I'm sure you will be proven wrong on that account. I've been using these machines since I was 3 since my dad was a computer engineer.. The things I've seen happen just during my lifetime makes me hesitate to say anything is impossible.

However, I hate it because machines break. If my phone breaks, I still want to be able to listen to my music.
