Apple has designed this amazing calendar app for the iPad. It looks just like a nice, well-designed desk calendar. And yet, to move forward in the calendar, I have to push an arrow button? Why not make it exactly like the iBooks app where I can turn pages by swiping my finger across the edge? iBooks has trained me to do that and it’s exactly what I try every time I’m using the calendar. Odd they didn’t implement that. I wonder what the reason is.
