Google has launched (US only currently) a 2 inch dongle that connects to your TV via HDMI. It has wireless functionality and you can stream things from it like Netflix etc, and control it using an Android product or Apple.
I think it could be really good but currently only available to US and goes on sale on Google Play, Amazon and Best Buy. I wouldn't chance buying one internationally as I have suspicions it wouldn't work but I'm sure people will test. It costs $35 so around £22 but just depends how much they charge us for it internationally.
