If you don't like spines and have the space, just have the front covers facing out. Ha ha.

I still prefer having the physical copies. Easy to misplace if you don't have a good system, but also easier to loan out. It may be 20th century, but until digital libraries of movies aren't such a hassle, it's what I'm sticking with. Honestly, I'd like it both ways. I like having the physical copies for looking at and loaning out, but I'd like them to come with the ability to back up identical copies to your computer for streaming throughout your home. Then you could easily make playlists of scenes for demoing your system or to have as background for parties, etc. That convenience is what I keep crossing my fingers for, but so far we're stuck between the 20th and 21st centuries.
