It's funny, Android fans will still tout how Apple is late to the game and their precious Moto 360 is round and was first. But I bet you over a million dollars that Motorola, LG and Samsung didn't go this far with their watch. Those other watch companies simply slapped Android Wear (or Samsung's own software like Tizen) on their watches and called it a day. Hey look, you got notifications.
Currently, I'm a first gen. Pebble owner, but come April 10th, I'll be placing my pre-order for the Apple Watch Sport. Despite the fact that I love my Pebble, I'll be the first to throw it under the bus when someone calls it a "smartwatch." The Pebble is not a smartwatch, it's a glorified notification taker on a watch. You can't respond to emails or read them in full, you can't take calls on it, you can only use a button to answer them. There's no maps or built-in fitness tracker, no speaker, it doesn't play music, it only controls it. You can't use it to pay for something or view instagram or photo libraries. Essentially, Pebble is a Streetsmart Watch, it's okay, but not brilliant.
With the Apple Watch, Apple really did take their time and spent years making sure what they brought to the market was different. Again, sure it can do notifications and maps like Android Wear, but it goes way beyond what Wear can do and this video and Apple's attention to research proves this, they are coming to the market prepared. Once apps are made specifically for the watch and are no longer companion apps, it's popularity will explode.
