Doesn't really impress me personally. I don't really see any actual use for myself for 2 screens. I'll rather have them make a screen that can be the primary display, but also permanently show stuff without draining battery much. Sorta like AMOLEDs on steroid
I miss having a screensaver clock on my N8 that had an AMOLED screen, but perhaps something a bit more visual than only that.
Don't see myself flipping my phone around constantly within a few years
