I purchased the Surface Type Cover and pre-ordered the Surface Pen separately, so those items are not included in my monthly payments. I am a Surface Pro fan and I look forward to being able to get the next new Surface Pro device when it comes out. I may choose to get the next iteration of the Surface Book or maybe the next Surface Laptop, but the point is, I have options with the Surface Plus Program. The Surface Plus Program gives you a way to get what you want.
Check out the official website for more information about the Surface Plus program.
