A Computer that can be Carried in a Memory Stick

         A group of scientists have come up with a new software that helps one carry his/her personal computer in a memory stick. The full Operating System (like Windows) can be stored inside the USB stick. When auser plugs the stick in a computer, that computer will restart into his/her personal set-up. Once the user has finished using it, no one will ever know of it. One just has to shut down the computer,put the USB stick back in the pocket, and the PC will never know it has been used.
       The personal set-up is named Tails. As everything the user does is contained within the Tails, the software on a stick , not a single trace is left on the original PC. That means no chance of cookies of websites browsed remaining in the PC, and no documents being left in the recycle bin.
