You would think from Apple’s TV ads for the Siri feature on the iPhone4S that Siri is technology from the future. The reality is though it doesn’t actually work as well as they show in the ads. And most of the time it doesn’t work at all since the processing of the voice recognition occurs server-side and apparently Apple have been having issues keeping the service up and/or available and you get a response something like: ‘I’m sorry, this service is unavailable right now. Please try again later’.
This article in Gizmodo gives the dirty low-down. It’s an interesting step forward, but in reality it’s just not ready for prime time yet.
