In his December 2004 discussion with Wired editor-in-chief Chris Anderson, Cory Doctorow pointed out that DRM:
[is being used] to sell you the same crap for more money.
[makes you buy] all your media over and over again.
Bandai is going to be the first company to package a DVD along with a UMD version of the same content to watch on your PlayStation Portable while on the go. […] You do have to pay extra for the bundle with the UMD in it (about ¥1,260, or $11.72), but at least it is less than what it would cost to buy each disc separately.
Although this looks like a sweet deal (you pay a lower price if you buy both DVD and UMD), the reality is that the DRM on both the DVD and UMD prevents you from porting the movie data between your computer and PSP (an otherwise perfectly allowed Me2Me use), thus forcing you to buy the same content twice.
Imagine a similar scenario being introduced to the music market: I can hardly believe consumers would pay for, say, a CCCD+ATRAC package (CCCD for your CD-player/computer, the ATRAC files for your Sony MP3 player).
