Now that I have my Blu-ray player in my PS3, I feel like I can start buying movies again, in that format. I stopped buying DVDs because it's time to move forward, and it sounds like I'm not alone: DVD sales have flatlined recently; whether that has to do with people waiting to see if they should commit to Blu-ray or movie downloads remains to be seen.
Luckily, my big DVD library doesn't qualify me as a hoarder since my player is backwards compatible, but I still remember my boyfriend insisting that I get rid of my haggard old VHS tapes (I wasn't watching them). I give crap to other people, too — when I ride in my mom's car, I inevitably pull out a few old cassette tapes and wave them around saying, "really?!"
It's hard to give up old formats though; many people don't, electing to keep old players around because they enjoy the format (like with records) or just don't want to give up things they own. So tell me: Are you hanging on to old formats — VHS, music cassettes, records, etc.?
