really? So Blackberries never used notification LED's? Or Sony's. Or Samsung's? Or Nexus devices? Or HTC phones? Or LG? You know, the phones that make up 80% of all smartphone sales worldwide.
The fact is, LED Notification is a standard on all smart phones. But since the iPhone isn't much of a smartphone, more of a feature phone with a touch display, it fits right in where it belongs.
Yet, a tacky gold iPhone will fit right in.
Sounds more like you are compensating for Apple's inferior technology and lack of innovation.
All that said, the Moto X does not have a notification LED, but their solution is absolutely perfect. I pull the phone out of my pocket and the screen pops on with my notifications. Put my phone on its wireless charger and it brings up the screensaver until a notification is received. Having the 'breathing' effect in the status bar is a nice touch. As long as you can see your phones display, from any reasonable distance, you will know if you have a notification. Although have a multi-coloired LED would have made this even better, but I'm guessing with all the wearable tech coming out in full force, this whole notification thing may become a moot point.
P.S. I fully expect Apple to copy and then attempt to patent MotoX's notification feature. Exactly what they did with Androids Notification Center and Blackberries Messenger service.
