Toshiba debuts a 4Gigabyte hard disk for mobile phones. The company has unveiled a 0.85inch disc that could deliver the large amounts of storage tomorrow’s phone users will require. With phones increasingly being used to play MP3s, video, and with TV tuners even coming to some models, the hard disk will enable users to store their own music and movies, and could even record TV programmes. However, competition is hot on the heels of Toshiba’s breakthrough, as Samsung has recently revealed its own 3Gigabyte music phone, the SGH-i300. Nokia too is set to debut a new phone in 2005 that also promises to incorporate a hard disk. Could this spell the end of MP3 players and USB disks?
