Speaking of smartphones, according to Tim Culpan, Olga Kharif, and Ashlee Vance of Bloomberg, online retailer Amazon is looking to get in the game along with other heavy hitters Apple, Google, and Microsoft:

A smartphone would give Amazon a wider range of low-priced hardware devices that bolster its strategy of making money from digital books, songs and movies. It would help Chief Executive Officer Jeff Bezos—who made a foray into tablets with the Kindle Fire—carve out a slice of the market for advanced wireless handsets.

As a bonus, the Bloomberg story also features this startling fact:

Manufacturers led by Samsung Electronics Co. and Apple shipped 398.4 million smartphones in the first quarter, according to researcher IDC.
