Whilst my iPhone is downloading iOS 7 right as I type, I wanted to go through the features that will make it brilliant. This is my personal opinion so disagree if you like.
Control Center
Control Center is like the Notification Center but for controlling your device. Swipe up and access all of your settings easily, much like Android's Quick Settings (it's getting a bit copy-cattish here now). Control Wi-Fi, Bluetooth, Do Not Disturb, a handy torch and more.
AirDrop
Us Mac users have had AirDrop for about 2 years, but it is the most used part of OS X that I use on a regular basis. Send files between Mac and Mac to make an easy file transfer. Now iOS 7 brings the same feature. You can easily share a photo with a friend who is running iOS or Mac OS X without the need for third party applications.
Notification Center
It's just so beautiful. It loses it's silly tweed background and goes for the full on iOS 7 design. The Today feature will be useful for me as I can check the weather, stocks (and yes, I constantly check stocks, mainly because I'm interested in the computing industry stock) and more.
Siri
Lord Siri will be updated as well. Apparently more voices are coming with it, but that's not what I am excited about. iOS 7's version of Siri will bring the ability to control the device much more. For instance, you can ask him to turn on Wi-Fi or Bluetooth. Great for when you are on a hands free like I am sometimes.
Safari
Safari has better performance. It also looks more attractive and the tabs are organised in a neater way that will suit every device. Tabs are shown from above, a bit like a magazine rack. It all looks awesome.
But to finish
I never mentioned how I do like the consistency of the new user interface. It is so much more consistent and coherent that iOS 6 and before. I am excited a lot about the interface and the new design is a change I will have to get used to, but it will be great to try something new, hopefully.
