have the Series 5 Ultra 8GB RAM now since a few days, brisk part, starting time max 10 Seconds, small and handy, on Win 8 you get used to, but have the UI replaced (no tiles please) and can not complain at the moment. - However, after 2 months is the device that requests the recovery to on, and again and again. Recovery completed, renewed request for recovery, sent in for repair to Regenersis (on invitation from Amazon), get back with the note no hardware fault could be detected, repeated repair request would be chargeable. They have the thing apparently started even once from the HD. Embarrassed, sad and obviously a sign of disinterest. Stay away from this unit, but may be good can quickly mutate into scrap in connection with the Service. Second repair attempt is successful, motherboard replaced, newly set up, of course, the most recently edited data is gone.
