Microsoft’s Surface Book 2 ships on November 16: 13.5-inch for $1,499 and 15-inch for $2,499

Microsoft today unveiled the Surface Book 2, available for the first time in two sizes: a 13.5-inch, like its predecessors, starting at $1,499 and a new 15-inch, the largest Surface laptop yet, starting at $2,499. Both feature up to 17 hours of battery life, a USB-C port, and the latest 8th-generation Intel Quad-Core processors. Surface Book 2 will be available for preorder on November 9 and starts shipping on November 16.

While the 13.5-inch for $1,499 succeeds the original Surface Book laptop released in November 2015, there’s also a 13.5-inch starting at $1,999 that succeeds the Surface Book i7 released in November 2016. As you might expect, this model is more powerful (i7 CPU and GPU in the base), but it is thicker (with fans) and less portable. The 15-inch only comes in the i7 version, which is more powerful but also thicker.
