Samsung and Google have announced a notebook computer that uses the Chrome operating system. Unlike other notebook and laptop computers, almost all user information is stored online 'in the cloud'.

The Samsung Series 5 Chromebook has a 12.1-inch screen and is just 2cm thick.

Global shipments of GPS-enabled GSM/WCDMA handsets increased almost 97% in 2010 to 295 million units, according to a new report from Berg Insight.

Shipments of GPS-equipped phones are expected to reach 940 million units in 2015, a compound annual growth rate of 28.8%.

New figures from Juniper Research suggest that 63% of data traffic generated by smartphones, tablets and feature phones will be carried by fixed networks - via WiFi and Femtocells - by 2015.

This annual amount of mobile data traffic 'offloaded' from mobile networks is expected to reach nearly 9000 petabytes by 2015, the equivalent of 11 billion movie downloads.

Welcome to this week's news summary from TheFonecast.com.

In Wednesday's podcast Iain joked that we ought to have a regular Olympics news story because everyone else was talking about the event constantly. Well, following the headlines about introducing WiFi to tube stations in time for London 2012 comes another Olympic news story.

London Underground is inviting telecoms companies to tender for providing public WiFi service across its network by June 2012. It follows last year's trial of WiFi technology at Charing Cross tube station.

The winning bidder will be given the go-ahead by the end of this year, which means the network could be in place for the 2012 Olympic and Paralympic Games.
