I think what Facebook are going for here makes a lot of sense.

The home screen at the moment is a fork in the road with the choice of dozens of different app paths to take. What they're planning on doing is removing the extra step needed to start interacting with the content.

It's similar to how they changed the original facebook app. Instead of starting by presenting all the options of which part of facebook you wanted to go to (profile/photos/newsfeed/messages etc.) it instead went straight into the news feed.

This presumably could work just as well with the whole phone. Although my concern is that facebook is only a small subset of my sources of interesting information on mobile. It seems highly limiting for it to only show facebook app content. Maybe there's a possible opportunity for a competing, open 'home screen' app to bring it all in.

This takes what Windows Phone did with People hub and applies it to the whole phone instead of restricting it to an area of the phone. Of course people hub brought over people from twitter, linkedin, etc. as well so is much more comprehensive than this.
