You'll be happy to know (or sad, depending on how you look at it) that your N9 is defective. It takes me 5 seconds at most from the home screen until I can hit shuffle, with all the loading, animations and whatnot, I never have the feeling that I am waiting. I also used the included USB cable to transfer my music to the phone, can't say I have experience with the ssh app.
The fact that you hit numbers in the dialing screen and have to wait a few seconds before the phone makes any sound is another strong indicator that your phone is broken and you need to have it replaced under warranty. It is not supposed to be behaving like that.
I have not seen any swipe conflict between the applications and the phone's UI, which is basically because for the built-in gestures you swipe from the edges, whereas for the apps you swipe from inside the window. I don't see how you can get a conflict out of that. Can you give me an example of app that does that? Seem like an app fault, not phone fault.
