The Mobile World Congress isn't just about an infinite number of similar handsets, operators trying to get anyone interested in mobile TV, and platform wars. Lots of companies have something just that little bit different on offer.

CSR — aka Cambridge Silicon Radio — shows off its eGPS technology.

This uses extremely accurate timing information extracted from mobile-phone network base stations to increase the accuracy and speed of GPS locations derived from satellite signals. At the show, they were getting around 10-nanosecond accuracy, or 10 billionths of a second.

eGPS doesn't need any specialist hardware beyond the ordinary GPS and GSM/3G radios; it takes between 20 and 100 MIPS of processor power, depending on what it's doing.

Put simply, what is the compelling reason to pay ~$200 extra for an Eee with Windows XP? A Windows Eee won't come with any useful applications and you'll have to buy anti-virus software to boot. The truth about low cost computing is that nobody really cares whether the machine is running Windows or Linux as long as its cheap, its easy to use and it works.
