k, so basically thes things called Xenobytes have been created some time ago. For those who don't know what they are, they are basically computer memory systems that are un-necessarily large. Closer to geek speak, it's approximately; 1,000 Terabytes, or 1,000,000 Gigabytes, or 1,024,000,000 Megabytes. Since it's not really necessary for anyone to actually have that much space on the computer besides the computers still trying to caculculate pi.
