For me, it's how can I get the slick and super convenient integrations between my phone, tablet, and laptop outside of Apple? I am talking about Handoff, Continuity, iPhone mirroring (can use my iPhone and its apps while it remains locked somewhere), AirDrop, Continuity Camera, universal clipboard, iMessage, etc.
