Side by side by side. If the iOS 6 home screen could be changed, I would make it three dimensional. Basically, expose and pages style. Picture this, one finger taps and holds in the lower corner of the screen while I swipe in any direction, revealing a new home screen with new apps that are appropriately grouped together. (think 6 faces/home screens on a cube) No more folders. Apps that get put into folders get forgotten. Now, you potentially have 9 max pages of apps X 6 home screens = 54 pages of apps that are categorized more efficiently. (and if you want folders, then yes, you can add them!) Apple, if you read this, (lol) and implement it without my conscent, you will hear from my legal team!!
