To you maybe, but nobody that I know that has an iphone worries about these mundane "problems". Our iPhones work, and work well doing all the things we want them to do. By the way, how are folks measuring these 0.5 sec. delays or whatever parameter they are using? LOL
It's not working as well if it's running slower though. Good for you if you can't notice it, but plenty of other people are, which is why this thread exists and why it's so lengthy. I don't know why you'd want to defend slower software.
