It's actually used on a near daily basis, but mostly to play blu ray Cinderella for my daughter.
I have played games on it in the last two years, though. The 21 month mark should coincide with the date of the gigantic privacy breach they had.

Well that's nice, I'm glad you have been keeping the dust off it, even though PSN misses you
