Plus, this will (potentially) play 10 or more systems:
-Famicom
-NES
-Super Famicom J/PAL
-SNES
-Mega Drive J/PAL
-Genesis
-Master System
-Game Boy
-Game Boy Color
-Game Boy Advance
-Possibly 32X with a system update
It plays them in HD, can do smoothing, save states, backup saves and copy them back to carts, has a built-in game genie, potentially will play every game thanks to system updates, potential for homebrew through its Android structure, and ports for 3 different classic controllers with the option to map any of them for any system any way you want - and it only has 1 HDMI cable and 1 power adapter.
For $100 that's a deal. Or...I guess I could buy 2 Call of Duty games.......yaaaaaaaaaaaaaaaaaaaaaaaaaaay

I bought an Ouya, and I can potentially play any game I want, but I just find that I prefer using cartridges, and I want a clean retro-gaming focused interface to do it. But I don't regret buying the Ouya as it's still fun every once in a while, and its a neat little gaming oddity.
