What some people like yourself and others fail to see is that the development changes are huge. Apple for the first time has opened up their app sandboxes allowing developers to talk to other apps.
This means companies like Google can add a "share" option to Safari that says "Share on Google+" or Adobe could add a share option in the photos app to "Open in Photoshop".
This is a really big deal with huge potential.
Agreed on this one with a few exceptions. On the front end and UI end, this is a good amount of catch up to what other platforms are doing, but that's ok. OS's and UI's are so much of a commodity that everyone is borrowing something from someone these days. Here is some potentials thoughts on the front end:
-Widgets: I think the new widgets is in a good location. Probably more useful in the notification center than on the home screen since it becomes accessible in any app. I don't have to go back home to see one piece of info. This would probably make the notification center actually usable for me since i thought it was rubbish before. I don't use them much on Android save for a few information displaying ones like Dashclock and the weather.
-Quick Reply: This one is big improvement. Have a quick conversation while you are in the middle of something is great.
-3rd party keyboards: Big one here. You can finally get the keyboard you want. I prefer Swiftkey to everything else.
-Improved Spotlight: one of my favorite features getting a bump.
Extensible API's: This one is huge. I'll go into a bit more below.
This release is chalk full of back end stuff. It leads to a ton of potential that will need to be realized. I have faith that the 3rd parties will fulfill the potential since it will give them more money. Here are my thoughts:
-Extensible API's: This is one of the big 4 i wanted to touch on. This let's apps share info back and forth. This one is huge if only for the share featrue. One of my biggest gripes with iOS was the lack of this. I love it in Android where I see an item and i want to share it. Previously in iOS, total pain. Now, hit the share button and select the app. Very useful for Pocket and other apps.
-Touch ID Opening up: Hopefully, we can use Touch ID like we wanted to last year. Let's see if we can auto fill passcodes. Or even better, if 1Password or Lastpass can integrate it so it works like it does on OS X or Windows.
-Metal: This one is big for games. Yes it moves to a more proprietary format, but if it delivers, i don't hear anyone but Dev's companing. This happens anyway in Windows where barely anyone uses Open GL, it's mostly Direct X since it works better for Windows that way. Same kind of thing here
-Swift- This will produce better apps since developers can focus on making apps quicker since it's easier to write and you get less errors.
So big thing that I see for iOS 8 is two fold. Catch up with front end UI features and a ton of potential on the back end. While yes, it's Beta 1, you aren't going to see everything yet, I have a feeling we are going to see some really nifty stuff at the end of the year.
