The reason the home screen is a row of apps is because Apple's focus has NEVER been the home screen.
It's all about the apps.
Actually, now that I think about it - my "desktop" is a big grid of "apps" and folders. So what exactly does being "desktop class" have to do with some additional "functionality" on the home screen.
Its a portal, a screen you aren't meant to be on long. Because all the work is done inside the apps. They are the stars in iOS - which is why app quality has always been better on iOS (though the gap has closed). Apple focuses on letting the OS retreat so the user can focus on the apps. Android tries to do everything in the OS, while the apps are secondary.
You like the way Android works, go buy Android.
You seem to be one of those Apple elitist that get all defensive if anyone so much as hints at one small dislike of anything out of Apple. As I stated in my original post, I love their ecosystem, but there's no reason for them to lock it down so damn tight. You say it's all about the 'apps', yet there's no room for Cydia or any of the apps that come out of there?
