Got this brand new Microsoft Surface Pro 3 from a company event, so yes it is LEGIT.

Specifications:
64GB, intel 3, comes with the tablet only (you need to buy the keyboard separately), stylus pen (with battery), charger.

Retail in Microsoft and Suning is 5688RMB. I saw in Taobao some are selling it for 4600RMB. I'm selling mine for 4000RMB.
