Facebook’s ‘Phone’ Is Another Triumph of Mediocrity

"Facebook's Mark Zuckerberg says the company's aim is to be the home screen of any Android mobile."

The long rumored Facebook phone turned out not to be a phone at all.It is a software called Facebook Home that makes it easier for people to spend more time on Facebook. 
A phone from HTC that comes pre-loaded with Facebook Home will  be available April 12, with AT&T as the carrier.

HTC First is the first "Facebook Home " optimized phone in the world.It will be available in four colors (black, white, red and pale blue) and it costs $99.99.

The idea behind the "Facebook Home " software is to bring Facebook content right to the home screen, rather than requiring users to check apps.
The main aim of introducing "Facebook Home " is to increase the number of people using Facebook from phones and tablet computers. Of its 1.06 billion monthly users, 680 million log in to Facebook using a mobile gadget.
The deeper mobile integration will likely help Facebook to attract more mobile advertisers.
