Our tablets and smart phones have this nifty feature known as "voice input", so on an Apple device it's called Siri and Android hasn't really given it a marketing name. Just today I was interested in the weather, so I asked both my Android phone and iPad tablet the same question, "What is the weather like right now?"
The good news is that both devices understood exactly what I asked for and presented me answers within a few seconds:
The bad news is that Apple's weather answer was wrong, because it stated, "It seems to be a bit windy out there". I wouldn't consider 3mph to be windy.
Another thing that I use voice input for is when I want to respond to a Text Message. It is much quicker to use voice input instead of hunting and pecking on the tiny virtual keyboard of a smart phone.
Enjoy using voice input on your phone and tablet devices, it works and will save you time.
