I believe it does come with a stylus and yes it is compatible with a Bluetooth keyboard.
However, I'd highly suggest the Nvidia Shield tablet instead, even though it is a little pricier, it has a lot better performance.
i know, the k1 is really starting to show of the power of Nvidia. But i want a tablet for School/gaming and therefore i want the stylus. ANy suggestions on tablets with stylus/Dock compability? my budget is 600 Usd, or 4000 Swedish Kronor.
