Technology has reached its finest. There is something related to a computer, called the iSpark (Much like the iPhone, though much more capable of things than the iPhone, seeing that it runs on Magic.). The iSpark allows its owner to watch Live Quidditch games, and contact other iSpark owners along with listening to music. Teachers, especially the elder ones, despise it because it 'goes against the rules of Magic', so be careful with using them in class.
Credit to this idea goes not to me but a friend. No me...none.
