Siri’s popularity has been somewhat of a controversial topic over the last 6 months. Although the digital assistant dropped some jaws when Apple introduced it to the public last fall, a lot of folks have since written the feature off as a novelty.

But according to a recent study from Parks Associates, a consulting firm, Siri is much more popular than you probably would’ve guessed. Surprisingly, 87% of iPhone 4S owners surveyed use at least one Siri-related feature each month…

Parks polled 482 iPhone 4S owners to try and gauge how popular Siri is 6 months after its introduction. As aforementioned, almost 90% of the participants admitted that they used the assistant on a monthly basis to complete one or more tasks.

It seems making phone calls and sending text messages were the most popular Siri-driven activities — roughly a third of those polled used the service for one of these actions. In contrast, 35% of the survey participants said they’ve never used the assistant to play music or schedule a meeting.

Perhaps the most interesting statistic from the report were the user satisfaction ratings. 55% of the iPhone 4S owners reported that they were satisfied with Siri, 9% claimed they were unsatisfied, and the rest were somewhere in the middle.

Apple still has Siri labeled as a ‘beta’ product, and is expected to drastically expand the digital assistant’s capabilities at some point in the future. It’ll be interesting to see where the feature is at two years from now.

What are your thoughts on Siri? Are you satisfied, unsatisfied?
