Droid squares off against iPhone for market share

In the opposing corner, a new smart-phone challenger: the Droid, powered by Mountain View, Calif., Internet juggernaut Google’s Android software, built by Motorola and sold by Verizon Wireless.

Verizon earlier this month offered a tantalizing peek at the Droid in an ad campaign with a slogan aimed directly at the iPhone: "Everything iDon’t, Droid Does."
