That is not the same though. I use this as a daily driver and I don't need to dedicate a display or keyboard for it, just use the ones I use for everything else and have the phone just as a normal window on my desktop. Also lots of phones are unable to output video at all. Such as all Google pixel/nexus devices ever made (unless I missed one).
