Ouya, the Android-based game console that arose out of a wildly successful Kickstarter campaign, officially launched today. The $99 device quickly sold out at a number of retailers, including Amazon and GameStop. "According to Ouya, the console currently has more than 170 downloadable games, as well as a built-in software development kit that enables people to create and test titles right from the hardware." Many reviews of the console suggest the controllers are not very good, and there are reports that the Wi-Fi connectivity can be flaky. There's also a lot of commentary about Ouya that clearly came from unrealistic expectations of what a $99 device can provide. Most of the backers from the Kickstarter campaign have received their consoles, but some are still waiting as Ouya tries to sort out shipping problems with DHL.
