Chinese outfit In Technology Group (ITG) has been beavering away on an AMD-powered mobile phone device that runs Windows XP.
Stories about the phone have been kicking about for a year now, but wee site UMPCPortal says it has heard that the device will cost around £240 for the lowest-spec device, rising to over £400 for the top-of-the-ranger. Not that there's much info about the full range available.
ITG said the phone is powered by an "AMD Super Mobile CPU", which doesn't actually exist but is likely to be some sort of Geode.
Whichever chip is in it, the device will come with a hard disk, full keyboard and run a version of XP and further blurr the distiction between phone and PC.
