I'm a fan of physical media. I still prefer discs to digital copies of movies. But with comics I just prefer digital. Being able to pull something up on my tablet if I'm away from home and have some time to kill is great. And it's nice to not have to worry about "being careful" like you do with actual comics. (Or at least I was always careful to not ding/rip/etc.) I always have a large backlog of comics to read because I always buy stuff for really good prices from the comixology sales.
