this is primarily a tool for piracy.
I purchased a samsung BD-UP5000 blu-ray/HD-DVD combo player (to take advantage of the uber-cheap HD-DVD's). I made this decision because I wanted to be legal and legit. Due to the DRM restrictions on blu-ray discs, some of the new discs coming out will not play on this device, even though it's a blu-ray player and plays others just fine. I contacted Samsung and because the product has been "end of life'd" I have no option but to purchase another device to play the newer blu-ray discs coming out.
How did DRM prevent from piracy and not just hurt me as a legitimate consumer? In fact, if I'd used the torrent services or other to get HD content movies and television shows, I wouldn't have been left in the DRM dust.
Putting locks on a car only really keeps the honest people honest. DRM is stupid and hurts consumers (like me). That being said, I've since purchased a PS3, because I desire to be an honest individual, but man did it make me feel dirty.
