Yeah the concept of owning Blu-rays depresses me when I think about it. You pay a lot of money, watch them once, if at all and that's it. In the end, like you, it's for the collectors purposes. Space Dandy is on it's way to me, and I always get buyers remorse when I buy a BD/DVD unless its some cool ass import...which usually just make me weep for my wallet.
EDIT:
I can see that. I just lie down on my back with my laptop on top of me, get under the covers and turn the lights off
It's almost ritualistic for me now.
That's also a good point
