Pre-orders for the SP4 still show ship by November 20th. I have read a couple of posts where people have been told at MS stores that they will ship on 10/26 with the other tablets. I was speaking to a MS guy at BB and his understanding was they were shipping 10/26 also. He was puzzled when I said the MS web store was showing 11/20. There was another post showing BB Canada shipping them on 10/26 also. It would be a pleasant surprise if they did ship on 10/26. The Surface Book i7s are also shipping on 10/26, but based on the PC World (?) article on the cpus, SB is using a different i7. The SB i7 uses the 520 gpu, the SP4 is suppose to be the iris 540. Anyone hear anything about the i7 ship dates?
