This thing is great for streaming video. We use google chrome because it uses half the ram Firefox does on this RAM scarce device. It boots on in little time.Do this if you want a fast computer:Right click " My Computer" or " This PC"More/Properties(Menu on left hand)Advanced system settingAdvanced - Settingsadjust for best performanceView picture for details. this helped speed this computer up. We only use it to stream tv, shows , hulu , etc.We like it better than a fire stick because it is easy to customize . The whole unit feels like a heat sink. I believe it dissipates heat using its outer case.  Gets warm like a phone that is in use but doesn't get really hot. We have it on a 1ft HDMI extension so it doesn't sit behind the tv and it hangs below to cool off and have easy access to the on button.For the price of a roku stick, get a windows stick. Do like the photo and you should be good.*You are responsible for your own system settings. Modify at your own risk.
