The new text messaging

Here I found a video about a new text messaging device where instead of manual typing in the message you want to send, you hold down a button and speak the words while the new device types the message up for you. In the video they time how long it takes a man to manually text a certain message and then time how long it takes to send the same message using the new device. The new device is quite faster then old text messaging, sometimes being a minute shorter in time. This is great and saves you time from typing the message but what boggles my mind is that most of the time while im texting, it is usually because I cannot speak out loud. In order to use this new device you have to speak the message you want the phone to type up for you, so it kind of defeats the purpose of being able to quietly send a message to someone. Although I do text message at certain times when it would be easier to use this new device, such as while I am driving, but most of the time it is because I cannot talk. I kind of feel like this is just like calling someone on your cell phone and just having a conversation. Although it may be helpful if you can speak out loud but the person your talking to is in a place where they cannot talk but most of the time I text because I cannot talk, so this device kind of seems pointless to me. I'm sure it will become the next big thing but I don't really see that much purpose in it.
