One of my biggest frustrations with WP8 was lack of true notifications, the toast notifications just went enough. So, the addition of notification center and quick actions is a huge step forward.
I've noticed that people who have the biggest problem with this is past Android users. I never really saw an issue with the start screen. As a toast message would pop up, then a number would show on the tile, or if you have it larger, it will show the last message.
With that being said, I tend to use it a lot and I have never, in depth used a Android device. It's a nice feature if you missed the toast popup..
Could I live with out it and go back to the 8.0 style ? Hmmmm....yea, I think I could but, it's just progress, people complained and they got it...It's not a bad feature once you get used to it but, it does take away from the live tiles....
No Cyan today....I really hope this is the week, this is really getting old....but, I think I have been through this on every Verizon phone I have owned...
