I know this topic has been beaten to death, but I thought I'd check in with you all. I've had my Space Gray Air for a little over a month now and have noticed a couple small nicks on the chamfer area (out of nowhere). I use a Smart Cover and take very good care of it (hasn't left the house). Is this something that is normal? For those of you with original Minis - have you accumulated a fair amount of these over time? I know buying something like the Smart Case would prevent this but I really prefer the Cover because it truly allows the Air's slim design to shine. Thanks for your feedback!
