The features of the Devkit are similar of that to the current OUYA, although the UI was much less polished, and many features were, as of then, un-implemented. The Devkit OUYAs can be updated and used as any other OUYA.
The Devkit controller is similar to the modern OUYA controller, although it was transparent, sported less-tactile analog sticks, and a different type of touchpad. These two issues were eventually fixed by OUYA Inc. thanks to feedback from the developers.
