Few of them require attunement, but the ones that do are actually fairly useful at lower levels.
I throw a lot of 'minor' magic items into games that are non-combat items. They're the things that a noble would commission to make their lives easier - a pair of shells that can cast message once per day, a rod that vibrates on command, a lens that can count similar objects that the user is viewing, a ring that cleans the wearer as prestidigitation, etc... We use technology a lot - nobles that have access to wizards would likely seek to obtain similar benefits.
