While I don't like how annoying Apple is with service upselling (iCloud, Music, Arcade), at least they moved iPhone backup from iTunes to Finder. So their local iPhone backup process is being maintained over time.
I don't have issues with my computer (PC or Mac) detecting my iPhone. Generally need to make sure iPhone is unlocked after plugging it in. What is tough is the large size of my iPhone (X gb) and how small my Mac's HD is (2X gb).
