A:Answer It is cheaper than the Surface Pro because of many factors. For one, the processor is a lot slower than the i5 (phenomenally slower than the more-expensive Core i7), and the Pentium included with the Surface Go is a dual-core CPU, while the Surface Pro has a quad-core CPU. Also, this model uses eMMC storage, which compared to the speed of an SSD, like that of the higher model Go and both Pro models, is like comparing a hard drive to a USB flash drive. In short, the storage in the Go is slower than the Pro. Also, this Surface Go model comes with 4GB or RAM, and I believe the Surface Pro includes either 4GB, 8GB, or 16GB of RAM. Another factor is screen size. With the screen being smaller, you end up using a lot less material when building the device, unlike the larger Surface Pro. The resolution of the Surface Pro is also higher than that of the Surface Go. The last big difference I noticed is the battery. The Pro boasts a 13.5 hour battery life, while the Go sits at a not-bad-but-not-as-good-as-the-Surface-Pro 9 hour battery life.
