There are plenty of good reasons to buy an iPhone already, but thus far none of them have been compelling enough for a cheapskate like me to make such a purchase. None, that is, until I saw this parody ad for the GLaDOSiri app, which, if it were real, would turn the voice recognition of an iPhone into an interface to everyone’s favourite sinister A.I. from the Portal franchise. Seriously, a GLaDOS app is the missing piece of the iPhone puzzle for me. If this existed, I wouldn’t even bother finishing this post before rushing out to the nearest Mac store.
