Google has cut the price of the Nexus 4 in handful of countries including the U.K. and the U.S., where the smartphone now costs from $199. The aggressive drop signals Google wanting to preempt the arrival of a cheaper iPhone. The price drop comes at an interesting time for the smartphone market. Google-owned Motorola's comeback device the Moto X has just gone on sale in the U.S. and Apple is expected to launch new phones in less than two weeks.
