Asus recently released their single board computer “Thinker Board”, modeled on the same form-factor and pin layout as the Raspberry Pi 2 and 3, and at the same price point. It comes with some interesting upgrades over the RPi 3: 2 GB RAM (over 1 GB); 1.8 GHz quad core (over 1.2 GHz quad) dedicated Realtek 1 Gb/s Ethernet; Realtek audio codec; and support for 4k HDMI out. It could make both a good media player platform, as well as a usable desktop box.
In their early review, Hackaday laments the lack of website and community. The former has since been addressed, and Asus’ official site is actually rather slick fun and informative, and includes a Debian based OS ISO and other downloads. They have also put up a Facebook page, but it’s mostly linked product reviews and blog post for now.
