In this advance, modern, and high tech world we live in, almost all the gadgets that are surfacing in the market nowadays are becoming smaller. For example, we used to have video home system (VHS) then, now we have digital video disc (DVD). Computer sets then are really big, but now we have computer laptop and Mac notebook, which we can easily bring and use whenever and wherever. Speaking of computer, do you still remember the time when we still use floppy disks to store date from our computers? Not anymore because now, we already have Universal Serial Bus, also known as USB, which is very small but has very big memory to store movies and mp3 music all you want. I do not see a problem with usb device other than the fact that it is so small that I would usually misplace it. Otherwise, this device is so cool because its storage memory is so big and you can use it to store as many files as you want. Look how far the human intelligence has reached huh?
