Love it or hate it, Apple's voice dictation software, Siri, is quite popular. If you live in a bustling city, it's not uncommon to see someone in a rush yelling into their iPhone in order to send texts, emails, or update calendars. Microsoft, regularly late to the party nowadays, is said to be working on its own version of Siri called Cortana -- named after the character from the Halo series -- that it will bring to all the major Microsoft devices.
