Mobile phones today are the called the Swiss knives of the technology world. They have everything right from a camera to a music editing software. The functions that are available on today’s mobile phones are unlimited, the only thing that is unlimited is the memory. Though there are many phone is the market that can carry up to 16 gigs of data and some might be coming in the next 2 to 3 months that will cary more than that like the iPhone 32 GB. But thats all, todays phones need to have memory that is massive to carry all your music and multimedia files and a battery life to support that memory. May be IBM was working on this and not they are working on a mobile storage technology that can store ten times the dat that is stored today on a normal mobile phone and also enhance the battery life. IBM’s racetrack technology will be able to store information inside the walls of the silicon wafers…cool. So once this memory commercializes it will be the death of PMP’s cause whey anybody will buy a PMP when you have a mobile phone with IBM’s racetrack technology.
