Yes, Cortana Voice, I am so looking forward to that addition to my phone... spoken reminders and updates are going to be a blessing because I sometimes forget to check my calendar. I will be able to key in doctors appointments, among other important events, and my phone will remind me in advance so I do not miss them.
I like the idea of the app store being overhauled. I thought for a while that it could be more intuitive and better organised. Hopefully the overhaul will make it more fluid and user friendly. Given my experience with Android, and instantly disliking the iPhone, the Windows Phone platform is the best there is and later in the year I hope to upgrade to the Lumia 1520 to take advantage of the larger screen.
