that's right
I guess that's what I'm challenging...why do I have to have pivots for keyboard and mouse use just becaue they're in my phone app? Windows 10 already toggles between desktop and tablet mode. That same toggle in desktop mode could take the pivot title content and make them buttons in the UI instead of a pivot (like the current UI proposed).
I don't think it's crazy to expect that some elements of the UX will be unique to a device where it makes sense...you can still tie the experiences together for visual consistency.
