Hubs with app views are just a modern take on legacy folders and files. The Games, Music + Videos, and People Hub got it right with related apps listed within their respective Hubs' "apps view." Music is where you'd think it is: Music + Videos, games are in the Games Hub, and instead of switching from app to app for information about a single person, the People Hub has all these services integrated into a single "app."
If there was a News + Weather Hub for news related apps, eBooks Hub for apps like Kindle, Nook, etc. TV Hub for service providers like AT&T, Time Warner Cable, Verizon, etc. have a single place for virtual remote control, DVR manager, etc., PIM Hub for calendars, tasks, & note apps., etc. This not only solves the "folder problem" but helps integrate more information into the UI and out of the developers traditional app specific UI.
