You know... Whether or not your mother is "lazy" is not the issue I see... You know your mom, and should know better IF this is who she is... So why on earth would you get mad at her for being who you already knew she was? If you knew she had an aversion to new technology... Why get her a phone that you already knew would be tough to get her to adapt to using? Sometimes the student is at fault for not learning the lesson... But often the teacher is not experienced enough as a teacher to know how to deliver that lesson OR know when a student doesn't have the prerequisites to be in the class.
