i’ll agree with darth. Smartphones are much more addicting- not in regard to viewing inappropriate material, but in regard to turning into a person who spends his whole life on whatsapp, etc. and speaking to siri instead of actual people (e.g. your spouse).
People forget that in a face-to-face conversation the person you are speaking to has k’dimah over your phone.
(i doubt that’s what you meant, but i’ll be dan you l’kaf zchus)
