Sorry for not responding earlier, but PCs and other devices come in more or less a way to look into the internet (of course...) although theremay be people attempting do a  matrix style (plugging yourself into the PC) way of getting through to the other side. Also, if there is a character with knowledge of programming, they might be able to even play god with the other world and manipulate it. (Not necessarily with good intentions mind you, and with debatable ethics of course.)
