You can quibble with the grades, but no doubt the discussion of each category is worth the read.
Two A’s, deserved in my opinion: Wearables (AirPods and AirPods Pro are home runs) and Hardware Reliability (surprising A, but my experience in recent hardware has been rock solid).
I think Jason Snell and John Gruber should consider adding Apple Store/Customer Service grades. Lots to discuss there.
