I’d say that’s critical to the best possible use case scenario for Siri on OS X. Only one major improvement came to Siri in iOS 8: the “Hey Siri” feature. Really, it just needs to be better at some things-and there’s no question that it is. But it doesn’t need to replace conventional inputs like keyboards, pointing devices, and remotes it can live along side them. Here’s the thing: too many people call Siri a failure because it’s not better at everything. There are certain features that I use it for frequently: checking the temperature, adding reminders to a list, sending texts while in the car, and so on. Siri has its detractors, but as folks like John Gruber have noted, it does seem to be improving, at least in terms of performance.
Yes, the speech-to-text dictation feature arrived in Mountain Lion and in Mavericks we got enhanced (read: offline) dictation. I know, right? We’ve had a voice-controlled intelligent assistant on our iPhones since 2011 and on our iPads since 2012, but on the Mac, nothing. Not on the list: “Hey Siri, why aren’t you on the Mac?”
