I'll keep buying DVD's as long as they keep selling them. I had a huge collection of videos, but then the DVD came along and I had to upgrade! I now have a large collection of DVD's, and I don't fancy upgrading them all. Luckily DVD's work on Blu Ray players so I don't need to upgrade yet!
I have 2 Blu Ray discs. The first is The Fourth Kind, which I only bought because I wanted to see what the Blu Ray quality was like. The quality was excellent, but I didn't enjoy the movie! The second is Avatar, which neeRAB to be seen in excellent quality. I won't be buying anymore Blu Ray's unless watching on DVD would ruin the experience.
