I can see why apple did it; the icon zooming in means that the icons in a folder are all in the same place as the little icons that make up the folder icon. However, the limitation is bad enough on an iPhone but completely ridiculous on an iPad. Curiously, if you look at Mavericks, you'll see that they've stuck with the old folder paradigm, (hopefully) showing that they see a problem with the 3x3 implementation on larger screens.
The other thing that bugs me is that text labels on the home screen and in the zooming animation (on other icons) are obviously below the icon, but when we view the zoomed in icon, the text label magically appears above the folder. I know that's nitpicking, but if you're going to sell me on the whole zooming in thing, you could at least make it consistent.
