I just received and am now connecting the OUYA, an open-source gaming system that was the biggest launch in KickStarter history, and which solidified said crowd-funding site as a legitimate way to launch new technology start ups without giving away the farm to venture capitalists.
As you can see, the hardware certainly looks impressive, and since there is no physical media drive is exceptionally small. Anytime your console is smaller than your controller, you have gained ground towards portability.
Setup so far has been easy: plug the unit into the wall and an available HDMI port on your TV, pair your controller via bluetooth, connect to your wireless network, and you are set. Since this is still beta, the software is constantly being tweaked, so my unit is updating now. Stay tuned for follow ups on game play!
OK, I've given this a few months for the game selection to improve and updates to work out the kinks, and I have to say that for an independent boot-strapped project this thing is pretty cool. Major developers are still being courted, and may not do much depending on what happens with the offering from Steam, but in all there is some great gaming action to be found here.
