Mostly because of Apple's engineering issues with say, their butterfly keyboard.
You must keep it in warranty (AppleCare) and even then that's only 3 years then you have to pay quite a bit to fix it.
If you are just typing and creating presentations, you either ignore these issues and get your Apple or you get something else.
Currently, I am looking for a Macbook price at around $1500. Can anyone suggest a good one? hope to use just for typing and create presentations. (Personal use)
