Couple of basic questions about the iPad mini 4, I'm used to the iPhones and MacBook Pro, so not have any experience of the iPad at all. Finally succumbed to one though
1) Out of interest why do they say this is 'in the box', what is that part that fills that hole in to make it square, circled in pic, mine doesn't look like that? That quarter is filled with a plug that sticks out. What makes that flush square and why? My adapter on the MacBook Pro looks like that, but that's not what is actually in the box.
2) Do you not see that white circle moving when you shut down the iPad like the iPhone?
3) Notice the lock sound is far louder on the iPhone than this is, It's barely audible, Is it controlled separately to the main volume? I know that iOS9 is not identical on phone to iPad but expected it to be louder than phone?
4) Anyone bought one of those £29 Apple front covers, can't believe it's a separate piece to the back cover, at that price. Are they worth the money? I notice it overlaps the right hand side and it's not flush to the iPad? And the back cover is even dearer? Any good recommends for a one piece version of these?
5) Can I charge the 5S with the same plug as the one that came with this?
Thanks for reading....
