got it this AM as well. Niiiice. heavier than I imagined, but not a biggie. taking me forever to move favorites from SP3 to SB. But got that done.
battery was at 30 when I turned it on, but in 2 hours or a little less it was fully charged. I noted that Battery 1 as charged first then 2 but a running "average" was displayed for all to see.
WiFi did come on right away, but have a wired connection as well which finally showed up after the drivers downloaded. Got all the "updates" plus a today firmware update that applied to both the SB and SP3.
Screen is nice, touch pad about perfect, and the KB is muuuch better to type on than the Surface detachable on the SP3.
