Every day.
While I’m walking/commuting, I have my headphones in and am listening to something, be it music, podcasts, or audiobooks. Even on days I don’t have anywhere to go I’ll go on a walk for about an hour and will be listening to something the whole time. I’d buy a phone without a camera before I bought one without a headphone jack.
They’ll skip 9 as that seems to be Kryptonite to tech. Both Microsoft and Apple decided to skip straight from 8 to 10 with Windows and iPhone respectively.
