When Microsoft designed the "Word Flow" software for the QWERTY, they did so with the intention to break various text-message speed records. And that is where the video below comes in. Back in January, Gaurav Sharma joined the Microsoft Research team and a representative from Guinness to see if "Word Flow" could take down one of the old records.
And sure enough, with a time of 18.44 seconds, the old Guinness record of 18.53 seconds went down. If you're a Windows Phone 8 user, you will soon see what the fuss is all about when "Word Flow" becomes available on your QWERTY, after the update to Windows Phone 8.1.
