It's been around long enough to have gained cromulence, I think.
I started using "OG" ~16 years ago to disambiguate the Motorola Droid that I had (which was the first Android phone available from Verizon) from the Droid 2, 3, and 4 that came later.
"OG Motorola Droid" has specificity, while "Motorola Droid 1" is something that never existed.
Yeah but 10 years late to be described as the original. That said, my parents got rid of their actual OG iPad only 2-3 years ago (did not hold a charge for a long time, finally decided it was time to get one that did).

Anyway, my usage is old enough to drive a car. :)
