This is what I use, and I love how responsive the Amazon FireTV remote is. I have the FireTV hidden behind my TV and the remote works from anywhere in the room regardless of if I'm pointing it at the device or not.
Now they use a accelerator/gyroscope and a dedicated RF channel to provide input. Plus that you can transmit also more data ( Wii remotes send the battery status too, for example ).
