So what do you think would be the best for emulation that no name chinese one the zero devices one or the cotton candy?
No idea yet as to exactly what kind of software support FXI will give.
OTOH it's pretty likely zero devices or whomever really makes that China stick will NEVER intentionally release any source code, but it's less than half the price of Cotton Candy, but almost double raspi. The MK802 is easily more powerful than the raspi and should be available again in a few weeks.
Really I'd say it's up to you if you'd be happy always likely just having Android 4.0 and maybe root + play store someday...
Me on these things I'd rather have source and the possibility of running a linux distro, so I'm still inclining for Cotton Candy, but MAY end up picking up something like this to see if it's useful. At the very least I could turn it into a franken android TV + emulator box...
Raspberry Pi's only real advantage is exposure of hw I/O -> hardware projects fairly easily, so I might still pick up one of those once they're actually available in quantity.
(The last time, a few weeks ago, that I trawled through the Android TV settop boxes on DX, I ended up opting to not experiment with one given that I knew that source release likelihood was virtually non-existent and decided to wait for something like cotton candy or another Google TV iteration...)
