My mom is in her mid-70s and she's been using an iPad and an iPhone for at least five years, maybe more. She's on iMessage and apparently my kids call and text her all the time.
My dad on the other hand, decided to check out on technology back in 1995 when TRW was letting old engineers go. He turned that into retirement and now unless it's really simple just doesn't bother.
But my dad is willingly refusing to embrace new learning. On a basic level I just have a problem with that.
Maybe it's just the teacher influence in me (mom was a teacher, wife and sister are teachers).
