I was brought up that the thought matters, if i think to call my mom she appreciates it i don't need to make some excess effort to show her i love her or show her more love.
You read your daughter a book off your phone you got for free, is that somehow worth less than a book you went to barnes and noble and paid full price for?
It's the difference between calling your mom and just saying "Hi mom, this is me thinking to call you. bye." vs calling her with a prepared thing to say/ask about that you had to take extra time to think about before calling. Effort went into that. You don't need to tell her "HOW" you came up with what you wanted to talk about, but there is a difference in how your call will be received as a result.
If you really believe that sending a text versus a hand written card will have no difference on how the message is interpreted, you should just know that you are in the minority.
I guess in Apple's example it looks like they're writing it as a document on MacOS, so I suppose they are writing it ahead of time.
