Started up easily, automatically connected to my wireless keyboard after I plugged in the usb dongle, automatically downloaded upgrade to Windows 10.  Really works well in every regard.  However, when I turned it off and tried to switch over to watch some Roku programming, it had somehow locked up my Roku. Had to reinstall the Roku which means signing in to Netflix etc all over again.  I'd probably give it one or two more stars if it hadn't messed up my Roku.
