Some of these features like 'Manual App Updates', 'Landscape Multitasking', etc. already answer a few concerns from the initial reviews. But biggest feature for me is number 10 in the list where Siri gives you an option to choose Google Maps or Apple Maps for directions. Wow! this is huge if it is a sign indicating what is yet to come. If Apple can come up with a elegant way of letting users choose default Apps like Calendar, Maps, Mails, Contacts, etc. believe this is the biggest thing that most iOS users would appreciate. Of course it has to be done in a way that it works perfectly fine for even the users who just want to use Apple's default Apps and not change anything.
