On October 26, 2015, the new Surface Book and Surface Pro 4 went on sale, and reviews across the internet began to pop up with hype and positive acceptance. Also, the way Microsoft advertised these new devices helped to make many people pre-order them right away, and they have become the must-have devices to run Windows 10. While we have been talking about these new portable computing devices and how great they are as advertised, after a few days since they have been available on the market, many new customers are now part of the Surface experience — some are newcomers, and others have upgraded from their previous version. No doubt about it, these are great devices. On the left side, you have the Surface Pro 4, which is the fourth iteration of perhaps the most popular tablet to run Windows that can also replace your laptop. The new tablet features a slightly 12.3-inch PixelSense display with a thinner and lighter body that looks almost identical to the Surface Pro 3 design.
