No Notification LED...WHY ?

Really? In all the years of having mobile phones from different manufacturers I've NEVER had an LED on them. Only ever seen an LED on Blackberry and newer Androids. Can you provide proof?

What you meant to say was "Every landline cordless phone or basestation has and LED or LCD display. That is completely different to having an LED.

I'd be willing to bet that the majority of mobile phones models don't have a notification LED. Feel free to produce links etc that prove me wrong.

No, more cell phones had an LED than did not a few years back. It was something smartphones just had, and was even on many flip phones. I don't doubt that you've never had an LED enabled phone, but your experiences are isolated. If you demand proof, well, I don't have the time to go through every phone that has ever existed with you. Looking at a picture of various phones won't work because many phones have them sort of hidden (under the speaker mesh, almost invisible when off because it's embedded in a black panel, sometimes the LED is actually beneath plastic and the LED just shines through, etc).
 
My previous phone, an HTC running Windows Mobile 5, had 2 such LEDs, used for various different notifications and purposes, and could even light up in different colors for different notifications. Really came in handy.

My current Bluetooth headset has NLED to let me know if I have a missed call when not wearing the headset. That means if I wake up in the morning, with my phone and Bluetooth headset on the table next to the bed, I can see the flashing NLED on the headset to let me know if I missed a call during the night. No flashing light means I can head straight to the shower without bothering to pick up and look at the phone. Would be nice if the phone had it, because I could leave the headset on the charger.
 
Was hoping that MS would provide one with the many improvements so far. Would be great to have one instead of having to constantly wave your hand of you're away from your phone and not within earshot to know you've received a notification.
