I have an SB and thinking of going SB2. I have two setups, one in UK and one in US with a Surface Dock I both. Don't want to buy new Docks, but I am just a bit worried that all the specs for the Dock still say that it is compatible with: Surface Laptop Surface Pro Surface Pro 3 Surface Pro 4 Surface Book No mention of SB2! Is it the same Dock?!
