The Surface Book 3 is a strange machine. It is unlike any other laptop, hybrid or tablet PC, essentially being a combination of all three: a proper articulated laptop with the screen docked and a full tablet when the screen is undocked.
Pros: excellent keyboard, great trackpad, brilliant screen, great stylus, good performance and battery life, Nvidia GeForce GTX 1650 discrete GPU, SD card slot, good cameras and mics, Windows Hello, screen comes off.
Cons: expensive, no 6 or 8-core processor options, relatively big and heavy, no Thunderbolt 3, only one USB-C.
