I am so happy with the quality of this device and using Steam Games was so easy. I have an expensive game computer and with this computer stick, I am able to use my high end graphics card in the bedroom, streamed to my 80 inch HDTV in the living room. I thought there would be a lag using steering wheel on Project Cars and there is none. The photo realism is breathtaking, and the sound out of my audiophile sound system is really fantastic. The use of windows on my HDTV is much faster than I thought was possible with this tiny computer. The antenna with this design is genius and the signal is full power. The stick runs warm, but not hot. I have not updated to 10 yet and I might not do it, because using 8.1 is too perfect to screw up. I feel 8.1 might work better than 10 and I want to hear more about 10 performance. This incredible stick is the finest one on the market at this time and the price is unreal for the power and performance. A perfect device for HDMI on HDTV and far exceeded all expectations. I am a science teacher for 35 years and my reviews are unbiased.
