The Nano Pi R1 is working well for me. Both wired interfaces work consistently and reliably. As Arne.F has pointed out, the 10/100 LAN interface will be limited in speed, if that is important to you.
I did not succeed in getting WiFi working, but I have neglegible experience with it. Instead, I use the WiFi on my ISP router occasionally. Another thread explains how to make it happen.
