I bought a new Surface Book today. I am quite impressed with it! I love the pen and how you can double click the top button on the pen and it brings up apps to use with the pen. I have tried detaching the tablet yet. I have alot of exploring to do yet. I am familiar with Windows 10 but not an expert by any means as I have had Macs for such a looong time. I am very happy so far with the Surface Book.
