Amazing to me

When I look at most TV remote controls, they have mostly the same layout. The remote itself is made of black injection moulded plastic and resembles a black brick that has been cut in the middle length ways. It is covered in about 50 little bubber buttons. The top of the remote is the "on and off" button and in the corner of the remote is the "source select" button. Lower down on the remote is number buttons, volume and channel up & down. Then there is a D-Pad for the settings I think. Then you have multi coloured red, green, blue and yellow buttons. Below that you have a load of buttons that don't do anything. Play, Pause rewind, select. 

I recently learned that the so called useless buttons are not useless, they are there to take control of devices that are connected to the TV, devices that support CEC. The HDMI port doesn't just send video one way, it allows the TV to send Remote signals back to the device, so if the TV and attached device both support CEC and the feature is turned on in the settings for both devices then the remote from the TV can control other things that are connected to it. 

You could have a TV with a Blueray player attached and have one control for both of them. Plus, the attached device doesn't need to be in sight of the remote, it could be duct taped to the back of the TV because it is the HDMI cable that is controlling it. 

To you this may not be amazing, but to me it is.
