I’ve had a Surface Book for five months or so and used it heavily, detatching it quite commonly; I’ve had it BSOD from detaching the screen once, 22 days ago. But I’m in the Insider Preview so I’m using pre-release software, so my experience is not necessarily representative. (It could plausibly crash more or less commonly.)

But on the build quality thing: I got a Surface Book because, as David said concerning the sword of Goliath, there is none like it. It’s not just build quality (which is really solid), it’s also the touchscreen and pen input and detachability.
