If you're one of those individuals who have been jealously waiting for you own chance to use Microsoft's new personal digital assistant, you might want to take some time to prepare yourself. I've been using Cortana for a while now and can honestly say that the more I allow her to integrate into my everyday life, the better and more efficient I become. My wife recently moved from Android to Windows Phone and her use of Cortana has my daughter pining for September when she can also move from Android to Windows Phone.
New Windows Phone 8.1 devices with Cortana pre-installed are coming. Windows Phone 8.1 is a wonderful smartphone experience, but it may be Cortana that wins Microsoft the market share.
Microsoft has released a video that gives an overview of what Cortana can do for you.
