I'm not too sure why people are expecting Siri clones to be good at this point. Apple had lots of resources, top employees of the country, and lots of time to develop Siri. 3rd parties are now trying to replicate this in a short amount of time using startup resources. They won't be perfect at this point. I love the fact that smaller companies are trying, however. The fact that Android doesn't really have a built in Siri like the IPhone actually intrigues me. The competition between new droid Siris should help drive a better app, assuming Google isn't hard at work on their own version
I was suspicious when the demo used what sounded like a woman's voice with a cheesy voice-mod rather than the actual product.
