When buying a Macbook, I know I'll be able to get parts and service for it - often from a local Apple store - for several years. If I buy a Dell N5040 today, and need service for it 2 years from now, will I be able to get it? That has never crossed my mind. I always just assume I can get anything on the internet. And largely this is true. For pretty much any machine I have, even custom built ones, I can easily replace everything within a week or so.
