Why Home won’t move the needle for Facebook

The announcement of Facebook Home this week has elicited applause, shock, horror, and disapproval. But it may not matter much anyway as the numbers suggest its reach will be modest at best.

It's a pretty long article, but basically the limited availability of Home on only several handsets, most users not needing something like Home since they already have the app, and the majority of users either using lower-end Android phones or iPhones and Blackberries, as well as battery life (all that photo syncing with FB) and privacy concerns, will ensure that Home won't be used by too many people.
