Usually new technologies are quickly adopted, especially for consumer electronics. If it's new and cool, consumers want it. Now. However, once in a while, old technologies linger even though better tech is available. Consider your home remote control. Most of us are still using the old fashioned IR (infrared) remotes that don't have much of a range, need to be pointed at whatever unit you are trying to control, and do not offer any interactivity. When using an IR remote you still need to watch the screen of whatever you are controlling to make sure you are on the right channel, to see if the volume is going up or down, to navigate menus and activate features. We usually do not have to point our electronic car key towards our car to lock or unlock it. You do not point your cell phone to a base station " for the simple reason that most likely you would not even know where the base station is. Our laptops don't have to be pointed at a Wi-Fi router. But we still need point our IR home electronics remote control at the television. If there is something in between us and the TV, or we are too far away, we know it won't work properly. It's a dinosaur. Link
