Android asks once, right after a new app is installed that has the ability to be default handler for that action. There's a slight annoyance factor here, but its taken care of quickly and its a lot easier to see this menu pop-up than dig through settings to manually handle what app controls what.

Meanwhile on my ipad, I feel like Apple is making all the choices and I just have to deal with it. This is the biggest difference between Apple and Android for me. My Android devices have the apps I like and 'just work' when launched or whatever. Apple forcibly opens the Apple apps and I need to run down my screens of installed apps to find what I actually want to run.

I don't know how in this day and age I can't choose my default handlers of a product I own.
