I disagree. I would love for Apple to integrate voice to text capabilities like Android has, where you can speak on any text input screen. This would be particularly useful while driving. I can look at my phone for 2 seconds to read a text message asking "When will you be home?" or something like that. It's a lot more effort to drive and type even a simple response like "15 mins" (not to mention, downright dangerous). If I could select a little button on the text message screen and say "15 minutes," and have it type it for me. That would definitely be useful for me. I currently use the Google app to do that if I want to google something quickly without typing it, but I would much prefer to use my default browser (iCab). We aren't talking about Star Trek here; just some functionality that would help speed things up a little bit.
I would say you have no right being behind the wheel. Forget about typing - "glancing at my phone for 2 seconds" and you have traveled 200 feet at 70 mph.
