Laptops that convert into tablets are like flying cars. Flying cars don't exist, because the gap between what makes a good car and what makes a good plane is insurmountably vast. There are great cars; there are great planes. No one has come up with a way to make a great car that's also a great plane.
Similarly, there's no such thing as a great laptop that's also a great tablet. The design differences, and user expectations for each, are too vast to pack into a single device. Microsoft knows this, and you can see it in the Surface lineup. The new Surface Book 3 is both a laptop and tablet, but it is very much a laptop that converts into a tablet. The Surface Go 2 is a tablet that can be used as a laptop. Neither are equally great in each category.
The Surface Book 3 feels very much like its predecessor, which my colleague David Pierce called "a serious computer for serious business." It's Microsoft's enterprise version to the consumer-facing Surface Go 2 and "prosumer" Surface Pro. The differences between the three machines come down to portability versus power, with the Surface Book 3 erring on the side of power.
