Does any one have an opinion about Chromecast

So here’s the deal guys. I have watched some reviews of Google Chromecast. I find this piece of hardware kind of interesting cause you can do really a lot with it. However I am not sure how it’s any different from Kodi or OpenElec for example? I have a media center on a raspberry pi that runs OpenElec and was looking to replace with Chromecast, but I am not really sure if this is the right move. Has anyone played with this device? Please provide any insights.
