My hi-fi has an sD card reader in it.
I never cared about this when I bought it; I was more concerned about it having the ability to switch itself on in the morning, and the ability to switch on at the same volume I last disabled it with (my last hi-fi had neither of these abilities; I had to race to the volume control to damp it down from a horrifying 14 before the digital radio managed to tune in every time I switched it on).
So I didn’t care much for the fact of a card reader’s existence; the rest of the hi-fi satisfied my criteria. But recently, I have found its presence… Rather liberating.
