Quad-core arms race 'ridiculous'

Microsoft Windows Phone Director Aaron Woodman has stated his belief that competition between manufacturers to produce phones with faster and faster quad-core processors is unnecessary. "The quad-core arms race is ridiculous," said Woodman. Instead, he explained how Windows Phone devices like the Nokia Lumia 800 are able to run fast without using battery-sucking quad-core innards. Microsoft has even gone as far as handing out €100 ($133) to anyone whose phone can beat a Windows Phone in a one-on-one user test during MWC.

LG's recently revealed Optimus Vu smartphone, which sports a 5-inch screen with an unusual 4:3 aspect ratio, won't be seen in the United Kingdom for at least a year. The long wait is due to the UK's lack of a 4G or LTE network. Other countries such as the United States are already enjoying super-fast 4G mobile data speeds while the UK lags behind.
