Two things occur to me with regard to Siri and its related voice recognition:
Even after several months, I still think it is magical. I use it all the time.
It’s unreliable. Particularly, the service is down about 20% of the time I use it. Sometimes when I just dictate with it (not using Siri but instead speech recognition), the service just fails. No blinking purple circles. No text. Just quiet failure.
The combination of these two factors is maddening. If the service blows and is unreliable, nobody cares. But combining “useful” with “unreliable” makes me want to break things. I suspect this problem is server related and fixable. However, there is a limit to everyone’s patience and fixing it needs to be a priority.
