New Surface Book owner -- looks like I've joined the club. I have an i7/512Go/16G RAM and a dock (lot 1541.) All updates applied. The dock is hooked mDP->DP to an external monitor (Dell U3014), Gigbit Ethernet and a Logitech wireless trackball. If I hot-dock the book and let it go to sleep and then wake it up (1) it seems to stop charging and the battery will drain to zero (2) icons on the desktop will start flashing -- both on the remote display and on the Surface Book display (3) the external monitor will go black from time to time.
I'm not using it for anything particularly challenging at this time -- just running a word processor (Scrivener,) One Note and the browser. But the plan is to have this running Adobe video editing software in the field next month, which should stress all parts of the system so it would be nice if I could depend on it.
