Terrible unboxing experience -- can't believe Siri was disabled by default and buried under general settings when I set-up the phone from my back-up. There's no easy way to get back to the Siri command list, it vanishes after you say something. Not documented anywhere.
Then Siri works less than she doesn't work. Right now she's thinking about a tough one -- "what can I say?" -- spinning and spinning "having trouble connecting to the network." Often she just vanishes with no error message given at all.
I also notice the Wifi icon switches to 3G and back -- often when Siri chokes. Maybe just another bug.
Siri also insists she can't figure out my location and tells me to turn on location services -- which are already on. Probably the same load issue -- the Siri server wouldn't process my location and respond in tme if it was overloaded -- but regardless the cause, the error handling logic is broken.
This isn't a beta, it's a bad joke. The vaunted artificial intelligence will likely star in the next week of Doonesbury comic strips. Even when she's working, Siri understood "What can I say or What can you do" but not "What commands can I say?" or "Show me the command list again" or many other similar variations. Not terribly the surprising -- the failed tech Siri is based on, the Personal Assistant That Learns (PAL), is no HAL either.
