At under $100, Ouya ($90, originally $100) is an open-source gaming system that's ready to seriously disrupt the gaming market. The console is affordable, especially when compared to the $400 PlayStation 4 and $500 Xbox One. All of its games are available in 1080p and completely free to try. Since it is Android-based, Ouya can run the platform's apps and stream TV shows, music, and movies onto the big screen as well.
You won't get any triple-A titles like Call of Duty, but there are plenty of fantastic indie offerings for Ouya.
