>If you're under 25ish, you probably had a smartphone while still in diapers

Circa 2004, when 25 year olds would probably be migrated out of diapers, smartphones were palm treos and Sony Ericsson K700s. I don't think they would be great distractions for kids, there certainly wouldn't be any endless Spiderman/Elsa YouTube to lock them in.
