Siri was a great concept when it (she?) was released. However, people didn’t find that it worked as well as they thought it would. With very little improvement over the years, Siri has gotten stagnant. Microsoft & Nokia use that to their advantage in a couple new ads. Cortana looks more advanced and useful than Siri. But, marketing can be deceiving. How’s Siri work for you, if you still use it?
