Yes, everyone should buy a smartwatch to get notified you got an email instead of a 1c LED on a phone.
Quite frankly, I'd rather have the watch then the LED; i know WHAT the notification is and if I need to respond immediately or not. All the other features such as music control are just icing on the cake. I get a ton of emails every day, some are unimportant, some are critical and require immediate assistance, most are in between. If I had to check the phone every time an LED indicated that email came in... Forget it.

Of course, till the day Apple decides to copy a feature, its useless (big phone, copy paste, notification, control center, widgets, wifi ac, keyboards) then suddenly it becomes 'magical' once they do.

What they put into the phones isn't what's magical - it's how it all works.
And you're saying that no one copies Apple? Heck, everyone said that the iPhone ITSELF was useless, would never gain any market share or make an impact in the mobile world, etc, etc, etc.
But hey, you're gonna want a list of things that were copied from the iPhone, so....
iPhone itself (connected music player, phone, and internet)
True web experience versus WAP
App Store
iTunes Store
Pinch-to-zoom/multitouch/Double-tap to zoom, etc.
Visual voicemail
Accelerometer & proximity detector
Seamless Wifi/Cellular integration/handoff
"Flick" based scrolling, with physics-based motion
Portrait/landscape mode
They also copied the design. Leading phones from various manufacturers before and after the original iPhone was introduced:
And let's not forget the words of the founders and initial developers of Android:
Reacting to Jobs' demonstration, former Apple engineering lead and early Android team member Chris DeSalvo stated, "As a consumer I was blown away. I wanted one immediately. But as a Google engineer, I thought 'We're going to have to start over.'""What we had suddenly looked just so — nineties" - Android developer Chris DeSalvo
Fred Vogelstein, in Dogfight: How Apple and Google Went to War and Started a Revolution quoted DeSalvo as observing, "what we had suddenly looked just so — nineties. It's just one of those things that are obvious when you see it'."
Android's founder Rubin was similarly quoted as responding, "Holy crap, I guess we're not going to ship that phone," a reference to the BlackBerry-like Android phone prototype Google was gearing up to release. Instead, the company had to return to the drawing board and develop a new device with Windows Mobile hardware developer HTC, which became the HTC Dream, also branded as T-Mobile G1.
If you knew anything about the history of smartphones, you'd know that Android is what it is because the iPhone exists, period. And while vendor X may include a feature that Apple later incorporates as well, it could easily be said that the copying started the other way 'round.
But then, only in smartphones so people get exercised about this.
