Personally I wouldn’t replace a Note with an S series phone.
Not really gaining anything noticable while sacrificing the functionality of the pen. Sure it has better specs, but not to the extent it changes the user experience.
I’m not shelling out $1400 for a new phone just because it benchmarks better or has slightly better battery life when I already get all day usage. Camera wise it’s probably better, still lacking compared to a $500 camera so I don’t rely on my phones for photography.
