What do you want to buy... Truth, I want to buy a Core m 10.8" Surface with a real SSD not eMMC with USB-C Fast Charging, USB3.1 10Gbps ports with USB-C connectors, DP 1.3 port with full spec support, DisplayPort /USB 3.1 Dock, Rock Solid Drivers all round not the erratic and random crashing garbage, but they don't make one. I don't know if they will make one. Just might wait to see if they do. Id want to buy an SP4 with the same premium features listed above I might have to wait for the S4/SP5/SB2 which hopefully would include these features. Without them I remain undecided about the SP4. For the SP/SB I don't mind it using the Surface Connect port for charging & docking but the connector should be moved next to the keyboard port so that devices in the SP5/SB2 lineup have interchangeable keyboards & docks. That would make the SB1 an orphan one off and the SP3 dock incompatible, so be it, the greater good would be served. You cannot really have a "Premium" device with weak buggy suboptimal drivers, beautiful hardware by itself is not enough. That's one area where MS needs to step up their game.
