I still wear my iwatch. I love how easily I can put it on with the sport band. I like that it's water resistant and doesn't start to smell after a while from sweat, unlike other watches I've owned. I like that it sets goals for how many calories to burn each day. and to exercise 30 mins. I like that when I'm working out at the gym I can check my heart rate, and also change the song playing and the volume without taking out my phone. I like that it reminds me to stand every hour. I like that the time (duh it's a watch) is always accurate. I like that I can check the weather date and basic information so easily. I like that when I charge it at night it has a clock that I can see right next to my bed. I like the subtle taps it gives you when you have a message or need to turn when using navigation. I like how force touching the screen is a way to access more functions of the watch rather than some redundant button or a touch icon that takes more screen space. The watch is honestly a nice accessory for those that like fitness, and a simpler way to get information and perform simple tasks at a glance. It does exactly as advertised.
That said, not everyone really needs this device, the same goes even for a regular watch. But for those who opt for it, will definitely have something that's more functional than the traditional watch. Hence smart watch.
As for all the smartwatches, I personally feel that the Apple watch seems to be the most intuitive and easy to use, while still retaining a lot of functionality. That seems to be Apple's trademark. SCW
