Money laundering is the process of transforming the profits of crime and corruption into ostensibly 'legitimate' assets.
The Surface Book is on the heavy side at around 1.5kg, but its footprint, at 31.23cm wide by 23.21cm deep, is perfectly acceptable for a laptop with a 13.5-inch screen. For the record, the Surface Pro 4 has a footprint of 29.21cm wide by 20.14cm deep. The hinge design adds a bit of height to the back of the chassis, so that when closed the Surface Book is relatively thick at the back -- 2.28cm, tapering to 1.3cm at the front.
Something similar to the GeForce 860M/960M would make the Surface Book a legitimate gaming contender. But based on what we've been able to see of the internal specs, the Nvidia hardware inside the Surface Book is actually closer to the entry-level Nvidia 940M GPU, which is not nearly as capable.
