Watching my wife get frustrated enough with Siri to fling her new iPhone 4S across the room and yell, ???Siri is useless!??? is enough to make me realize that I don’t need or want Siri. I have an iPhone 4, so I don’t have a choice but even if I did, I wouldn’t use it. I’m sure some people find it useful and helpful but I’m not one of them. Neither is my wife. Our 18-year-old son doesn’t use Siri on his 4S either. I believe he colorfully compared Siri’s usefulness to the operational nature of a vacuum cleaner.
