Point - keyboard reliability should not be a concern on buying a high priced laptop. Not in 2016, 2017, and 2018. Apple used to make a reliable keyboard, and instead decided to make one that was less reliable.
>I don't think the MacBook keyboard is an issue.
It does. I have personally experienced problems with mine. Apple has a warranty extended to cover the problem. There is a problem with the keyboard. Beyond that its loud and clicky - and distracting in a quiet environment.
Know what else shouldnt be a reliability concern on a modern laptop? Screen backlight failure due to how/how often the laptop is opened.
On a premium laptop, which these are, because spec wise we pay the most for an Apple product, having common failures of keyboard and now failures of weak, short, poorly designed ribbon cables that arent serviceable do not say "premium" - in fact it says the exact opposite.
