Made for Media Center
Everything and everyone needs an app store and if the platform's developer isn't willing to make it happen, then those in the community will step up to make it happen. In the case of Windows Media Center the 3rd party plug-in ecosystem has always been one of the platform's biggest perks, but what Made for Media Center does is bring all these apps to you via a 10-foot interface and the ability to install 'em without breaking out a mouse or keyboard -- can't beat that. Right now everything seems to be free and at first glance it appears that all of our favorites are there. If you use Media Center there really isn't a reason not to check this one out.
