SHEESH! I just love it when someone who does not use a device, tries to tell us who do use a device all the shortcomings of the device. Who ever said I use SIRI to dictate my writing? SIRI is not the only means of dictating on a Mac or an iOS device. You can just click on the microphone on the keyboard and start dictating.
“and although Mavericks still got a very high B, if you were to dictate a passage of 10,000 words, the text would have more than 1000 errors if you used Mavericks’s Dictation tool”
