My concern is about the application open animation. It's the same as on blackberry 10 (move to multitasking view then zoom in) and it's cumbersome, and slow. Please make the apps open immediately, even if they only show a splash screen for a few seconds. Simple transitions (zooming in from the icon, or fading/sliding in) are welcome, they give a nice touch, but the S60v5/BB10 slow and multi-step animations are really tiresome. S60 at least allowed the user to turn them off, and guess what, it felt like you overclocked the phone.
