The Autobots and Decepticons are locked in the eternal struggle for the All Spark (spelled as two words in the movie). The former clan wants it to rebuild its home world Cybertron and end the war, while the latter wants it to transform Earth's technology for its own benefit and conquer the universe. When falling into the hands of a USB geek, the All Spark would transform into a 4-port USB hub; and given its size, it seems an overkill. Keep in mind though, the manufacturer won't be responsible your USB missile launcher is brought to life.
The £17.99 All Spark hub is definitely one way of cluttering up your desktop while the in-desk hub is the exact opposite, putting unused grommet holes to good use.
