I do however have the MINIX model at http://www.amazon.com/gp/product/B00AA9K2GI/ and it seems pretty stable and not much to report. I used some logitech wireless mouse and an amazonbasics android bluetooth keyboard.
I wonder if you guys have heard about the Dreamworks MK802 Mini Android Computer sold by AliExpress in China for $38.70 U.S. dollars. It has everything that the Roku 3 does plus a full browser and e-mail capabilities. It also comes loaded with apps and you can download many more. I have one and it works fine. It took quite a while to get it out of China, however. Some of the specs are:
Op system: Android 4
Main chip : Aliwinner A10 1.5 GHz
Memory: 1 GB
Storage: 4GB, expandable to 32GB
IO/Ports: Micro USB/USB2.0/OTG and host expand/HDMI 1080P & 2160P
Power input: 5V-2A
Unit Size: 8.8x3.5x2 cm
