Notification center interferes with full-screen apps (incl. games)

No, the fact that Apple "are very unlikely to add an option to disable notifications" isn't "fair enough". When I bought my iPod it didn't have the notification center taking up half my RAM, slowing down my whole device and using up the battery twice as fast. It also didn't have a permanent link to the iTunes Store in the Music App (which, until I get used to, will press 1000 times).

It also had an operating system designed for iPod touch of the 3rd generation and not for the iPhone 4S or the iPad and wasn't sluggish and laggy. I can't seem to understand why they even have the right of changing my device's operating system every now and then and don't give me the option to roll back.

I want to roll back to version 3.1.3, or at least have the option to totally disable this stupid notification center and remove the ad of the iTunes Store from my Music App. If Apple doesn't give me the option, I will find other ways.

In this last update I saw several new stuff, but no respect to clients who don't have the money to buy an iPhone 4S and stick to their "old" devices (which isn't even 2 years old).

I agree with both posts and have the exact same issues with iOs 5. I also feel that I've been juked by Apple into upgrading to iOs 5. I had absolutely no desire to slow down my games and add a feature that would interfere with said games, which is all I've gotten with the notification center. No disable option? Seriously, that is just one of the most absurd things I can imagine.

And I hate to burst Apple's bubble, but your CPUs and iOs do NOT multi-task unless it's the 4s (which has two cores). If you (Apple) have the notification center running in the background at the same time that I'm playing my game or typing, the iphone 4 and all versions before it are going to lag or skip while processing the notification center while it ignores the current thread (ie games, interface, etc)! This is the reason the old system was implemented the way it was. I know this for a fact (for example, any games would pause immediately when you recieved a text message, because the iphone is only capable of processing 1 thread).

Honestly, I think apple intentionally added this feature in this way to try to force users to migrate to the 4s because it's a dual core phone, and it won't experience as much lag when running two tasks.

Just add a disable option, some people NEED the performance we had in iOs 4!

Thank you for supporting my opinion. As you already said, I feel as well that I am being forced to buy a new iPod, it seems as though iOS 5 is a strange type of advertisement of Apple's newer products which I won't buy even if my iPod totally stops working. I'm so angry at Apple that I won't even consider buying an iMac if they don't change their update policy. Windows may suck compared to the Mac, but at least they let you do whatever you want with your computer and this gives me the freedom to have really my personal device, exactly the way I want it to be.

I hate notification center and I see it as a "bug". I dont use it but still an empy grey screen comes down. It must automaticly be disabled if nothing is on right?
