As a Surface Pro 4 owner, the design is great but the drivers are awful and the entire thing feels hacked together software wise. I need more convincing. A colleague with a Surface Book suffers the same fate.
Sadly I won't be buying Apple either, as two new touchbar Mac Pros I've had have reliability issues (sticking key on one, crashes from the Thunderbolt driver on another).
Can't beat the previous gen Macbook Pros for reliability, user experience and ruggedness.
