Not good news for MS, though I will say that my Surface Book has been problem free (knocks on wood).
I bought the Surface Pro 4 when the price was knocked down to $850 (which included the keyboard and pen). The main reason I bought was that I just gave up on Apple coming out with the refreshed MacBook and the Surface was $350 less.
I bought it mainly for traveling. So far it's been a great unit for the price. Does everything I want. Far as I'm concerned, it's a keeper.
