Does anyone like having both Blu-ray and digital copies?

[Kochore]

Just curious because, I notice a lot of people giving away digital copies, even if they're not movies that they own. For me, I like having a digital copy for the convenience, if I have to take a movie on the go, I have the digital copy. I even use vudu disc to digital to back up those that normally don't come with a redeem slip. But, I also hold onto the blu-ray disc because, god forbid Vudu shuts down or anything, I have the blu-ray as back up (plus, the disc does have better quality)

So what about you guys? Thoughts? I'm just curious here
