So far, so good.
I'm impressed - even after all the problems getting one to work.
If your TV cannot stream natively, this would be a good and economical option for Netflix, Hulu, etc. And, I would expect HA related apps to begin to appear (any Android app should be an option). I spent $85 for MK808, K400 keyboard and 2A power supply and now have a 50 inch tablet with wireless keyboard/touchpad.
One problem is that it runs Android and every Tom, Dick, Harry and Louise has created their own firmware versions so, aside from the too many cooks issue, you never really know the origin nor what might be hidden in the code (Android malware has already reared its ugly head). The less adventurous are advised to wait a few months for Dell's offering. For other bleeding edge geeks, plunge right in.
There is a newer MK812 which has a 2.1A power supply, aluminum case and external WiFi antenna. It also has both HDMI and AV cables. It runs Android 4.2. Had I researched things a bit more before plunging into the deep end of the pool, I might have opted for the MK812.
The MK812 also has a good user manual (the one for the MK808 is abysmal).
The miniAndroid PC home page...
There's an Android app that can control it from an Android Smartphone (or tablet), saving the cost of a keyboard.
I recommend using Amazon (if they ship it, returns/refunds are simple) or paying with PayPal (refunds take a week or so).
It should be possible to control a CM15A directly with this device using the USB OTG connection. I believe the CM15A is an HID class device (i.e. like a keyboard or mouse) but I'll leave that to others (my preference is to replace the CM15A microcontroller to allow full direct control of PLC & RF).
