Maximum PC: Starting soon, pretty much any smartphone you buy will come with a virtual helper. Microsoft's Windows Phone platform has Cortana, Apple's iOS software has Siri, Google's Android OS has Google Now, and beginning with BlackBerry 10.3, BlackBerry users will have BlackBerry Assistant to boss around and ask for help. BlackBerry Assistant is the Canadian handset maker's equivalent to all the others, and it will act similarly.
Blackberry is trying too hard already. Microsoft's Cortana really impressed me in the World Cup and I am not sure any virtual assistance can get close at the moment.
