"After the murder of his uncle and guardian, the MI6 British spy agency recruits the reluctant 14-year-old Alex Rider to take over his uncle's mission. Like any good spy, during training he receives his key piece of gadgetry: a Hot Rod Red Nintendo DS. He also gets several game cards that transform his DS into an eavesdropping device, a wiretap detector or a smoke bomb."
Uhm, why can't our dual-screened wonders do all that? I wonder if the villains use PSPs which fire out UMDs at rapid speeds. Oh snap.
