I love this device, We use it as a PC connected to our Roku TV in the living room, and the Projector in the bed room (yes we watch movies in bed, projected on the ceiling)The Roku can't surf the web and the projector needs a computer, this little wonder does the trick. It is a full-fledged Windows 10 computer the plugs directly into your HDMI port just like a jump drive plugs into a USB port. I have a wireless keyboard and I am good to go in bed or on the couch.I will take it with me on my next vacation and plug it into the HDMI port on the TV in the hotel (they all have one).I would not use it as my primary computer, but it's great for that 'extra' machine you want to move from place to place.
