This board seems to work well for me with Armbian once I'd resolved the power supply issue. I'm running the ethernet link at 1G, sound is provided by an external CM108 device. I'm mainly using it for light desktop work, browsing using Chromium and also running the Arduino IDE. Compared to a Pi3 it does all these tasks faster.
