The Smart Cover is a brilliant accessory.. really lightweight, doesn't add much bulk to the iPad and still protects the screen. When I upgraded to the iPad Air 4 2020 from my Air 2, I looked high and low for a Smart Cover.. yet there are only cases and Apple's Smart Folio.. none of which come close to the 80g Smart Cover.. which got me thinking.... WHY?!!
Here's the answer.. magnets!
When you check the left side of the iPad, Apple have less magnets than they had in previous iterations of the Air (or standard iPad), which means there can never be a Smart Cover for the Air 4 or Pro 11, which is a real shame in my opinion.
