I use the google version when driving to attempt to send SMS, make calls, set reminders and update driving directions. It's hit and miss. Google has some serious pain points like locking the screen and functionality right after a last command while driving meanig you need to unlock to do a next item. And most annoyingly you can set directions but I cant get the thing to actually start navigating. I bought a windows phone that was on special recently to test and found Cortanta surprisingly better to use than the OK Google version. If someone nails voice it will be a significant decision making variable in my OS choice. It feel like both MS and Google are close but they need a new 'Steve Jobs' than has that last level of attention to detail and making it work in a practical environment. It feels to me it's more this lack of thinking through the UX is the bigger issue than the technology capability right now. I envy anyone working on this as it will be super interesting getting this right over coming years.
