I watched the video. Siri worked most of the time. Siri didn't work when he didn't have the songs he requested, didn't have a list with the title "Band Names" and he didn't hit the OK button when he wanted to be called "Rock God" after he finally says it clearly. Seems like Siri worked as well as can be expected. What's your point again?

Really, an iPhone isn't a luxury item? I suppose the auto parking feature on certain luxury cars works exactly like it does in the commercials. And I love the way navigating devices like Garmin or Tom Tom ALWAYS take you in the right direction and never lose the satellite signal. These devices frequently fail in the ONLY job they are supposed to do but I guess that's ok for them
