Microsoft has cut the barrier of entry for the Surface Book by US$200 on both the high and low ends by offering i5/128GB/8GB as well as i7/1TB/16GB SKUs without dedicated GPUs. While the Surface Book is still running on Skylake and lacks Thunderbolt 3 or USB Type-C, it is still an attractive device due to its unique design, active stylus, and solid build quality.
