ipod nano 7th, volume as sensitive as 5th gen nano?

My old Nano (5th gen?) with the click wheel, had a nice variation offered for volume control

but... it's getting old....

I'm looking at the 7th gen Nano... noticed it has the toggle type volume up/down

I've found on cell phones often the steps between the volume levels on this type of control is not "stepped" enough so I end up with a choice of too loud or too soft and nothing between....

I also wear the 5th gen Nano on a cord around my neck, listening to audiobooks and I work/do house chores/exercise/meditate.... etc... it weighed little and the click wheel was not sensitive to changing sections or volume if I bumped it

the new nano.... do you have to carry it around? noticed none of the cases I have seen are "wearable" and honestly, a belt hook will not work and I don't want an uncomfortable strap on my arm (often do my dance practice listening to the music on the Nano, would hang up on the veil)

sorry to the old click wheel go...

but, looking forward to 16 gb ;-)

those who have had the older Nano and now have the new, any advice about what I will find changed and what I may love in the new version?

thank you
