Yeah, the thing is, isn't that what every other company has been offering for a long time? All those features you've mentioned have been available before Apple even introduced the Watch, and people weren't so happy with them and didn't think the smartwatch is worth the price for those features. Then people thought Apple would find a way to make smartwatch some worthy new category and waited for them to introduce one, and when it did, it was nothing different from other smartwatches, except the haptic feedback. Don't think I'll pay extra $$ just for that fancy vibration.Funny, many of us that own them find them very useful. Love mine for notifications. It's great for fitness tracking. The "home screen" as you call it is filled with info. Sure you can have it as a simple watch face but you can also have it include temp, workout info, and much more.
In the time it takes to pull your phone from your pocket, I can tell you the time, the temp outside, and how far along I am on my workout goals for the day, and more.
Just because you don't see the use in having such a watch doesn't mean that millions of others don't also. There's a reason the Apple Watch has the highest satisfaction rate of any smart watch on the market.
I love my iPhone & iPad, and am also planning to get my first MacBook pretty soon. I'd gladly pay $2k for MacBook because it's worth every single penny I pay for it. But the Watch? For those features above, telling temp and workout info, and giving notifications, $350 for base model (Series 1 is cheaper but that's basically the first gen watch with newer CPU) is way too expensive.
