Later today (5 January), Google is set to unveil its own smart phone, challenging Apple's iPhone for market leadership in this area.

The device, Nexus One, is being manufactured by HTC, itself a strong contender in the smart phone market.
Analysts believe Google's move into the mobile hardware market could herald a new shift in the Internet paradigm as mobile usage overtakes PC surfing.
In an interview with the New York Times, Google's vice-president: engineering Vic Gundotra is quoted as saying: “We are incredibly excited about the opportunities that we see in mobile. We have invested a considerable amount, and we can now really provide a compelling mobile experience.”
Unlike the iPhone, the Nexus One will be sold "unlocked", so users acn opt for their own network, service plans and applications.
It will be based on Google's own Android operating system.
