The springboard is one of the things that annoys me the most about iOS. It takes simplicity too far, having each app be its own icon and all apps forced to appear there. I've got a lot of apps installed and the most irritating thing about the home screen is having to remember: ok, now what page is that app on? This is one area that I think Android (even with stock launcher) did much better. The home screen is where your most commonly used apps go (old style Windows desktop, anyone?) and you can pull down an apps list to get the rest. Much simpler.
And yes, I know about spotlight search, but having to type in part of the name of an app I'm looking for isn't exactly the most productive way to go on a device with a 4-inch screen.
