I had this surface book for one semester and now selling it for an upgrade. It comes with Windows 10 Pro, Intel i5 6300U 2.4GHz 2.5GHz 128GB Solid state drive (SSD) 8GB of RAM original power cord as well as the original stylus AND an extra Microsoft surface mouse which I purchased separately. Here is the intro from Microsoft store: https://www.microsoft.com/en-ca/p/surface-book/8txj08q9lxdt/4KV4?lc=4105&activetab=pivot:overviewtab The laptop has almost no signs of wear and I have put tempered glass for the screen and sticker cover around the body since the day I purchased. If you are interested, please fell free to contact me:)
