This worked great for 5 months, now it won't boot.  We tried several different flash drives & Chrome recovery, no deal.  I am guessing there is an intermittent HW failure in the device that keeps causing the failures.  One of the failure/reboots after reset with paperclip said there wasn't enough power to boot.  Checked HP Site, mine was commissioned in 2014.Buyer beware what you are getting.  If you want a decent device that is covered for 90 days you are good.  After that, well, fingers crossed.  Might be better off getting a new one.
