Competition to Siri

The BBC has an article about Microsoft, playing catch-up as usual:

Microsoft has been showcasing a new virtual assistant as part of an upcoming update for Windows phones.
The assistant, named Cortana, tries to be chatty like Siri on Apple's iPhones and iPads, while anticipating information you might want, like Google Now on Android devices.
Somewhere there's a clip of the presentation by Microsoft corporate vice president Joe Belfiore (photo), but Rico can't find it...

Rico says he can only imagine an on-line conversation between Siri and Cortana:

"Hello, bitch."
"Hello, yourself, you electronic whore."
"Why don't you..."

(You get the idea.)
