That home screen reminds me of Android. While there's nothing wrong with that, the point of Apple products is that they're aesthetically pleasing.

The lock screen just displays your wallpaper, and is actually one of the only places you can see your wallpaper without clutter. It's clean, simple, minimalist. Adding widgets and text and shit all over it is the exact opposite of that.

And frankly, that's a big selling point for the iPhone (and apple products in general). That's actually the point.
