New research set to be released this week found that 87% of those who own Appleā€™s iPhone 4S use at least one feature of its Siri virtual assistant monthly.

But most usage is across a relatively limited set of functions, according to consulting group Parks Associates, which surveyed 482 owners of the iPhone 4S, the only device to carry the service.


Well, that's pretty good seeing as the service is only in beta.
