I do not know, I tested and I love. In fact I did not know anyone around me who could advise me on the Chromebook is not common! After 3 days of use I am amazed, start in 3 seconds shows in hand, fast internet surfing and ultra-responsive, launch videos, instant pictures !!! PC & MAC are completely dumped nearby. The update is automatic and transparent. Tested with Plex and Netflix video playback is that happiness! The system is clean and very simple; second home PC is great, because the weak point is the closure of the system, small flat for use photo editing and word processing, is a somewhat limited, but possible. Parcontre no 3D games or video editing .... everything is perfect and even better. I tested with visio appear.in with integrated webcam and a USB Logitech immediately recognized unmanned Really great addition ... do not hesitate!
