Apple’s voice-controlled personal assistant could be better; here’s how. When Apple’s new iPad was unveiled last week, one of the features users had hoped for didn’t come with it. Siri, the voice-controlled personal assistant that’s been such a hit on the iPhone 4S, wasn’t among the tablet’s new features. (Apple did add a dictation feature, but it has none of Siri’s interactivity; all you can do is one-way dictation.)
