Well, I can explain myself on this one... You see, I only buy DVDs/Blu-Rays of things I AM going to be watching more than once, especially when they come with bonus features up the wazoo! The again, I have yet to, at least, "embrace" the digital side of owning shows/movies, despite the various combo packs I've bought over the years that do come with digital copies, because of how intangible it is in comparison to DVDs/Blu-Rays...
Don't get me wrong... I respect digital copies of shows/movies, especially for those that see it as the more convenient alternative to their viewing habits and the like, but I honestly have yet to get on board with going full-digital, for example, because I still like the feeling of holding something physical that I own, even if it is just a [legal] copy in the long run...
