Summary: This computer is configured and sold as a mini-media center. Yet it will not stream Amazon Prime Movies. The Video is horrendous. I don't believe there is a fix. If your thinking of running Windows 8 forget it. I spent the weekend working with Lenovo and Microsoft trying to get Windows 8 to run properly. It did not happen. Lenovo finally admitted it would not work. Yet the Lenovo website leads you to believe you can do the upgrade.
Summary: I purchased this nettop to do basic HTPC functions.(stream video from popular online sources as well as my network storage and video photos and local video). The overall video playback was very poor. Lots of choppy video with tearing and freezing. I spent hours updating network, graphics and chipset drivers to the most current versions, then configuring the OS to get the best possible video performance.
