What scares me is the legal ramifications of licensing as opposed to ownership. People with vast Kindle libraries may think they own their books...but they don't. All media is going to go down this path, and I worry about consumer rights.
*Edit*
Googling around a bit it sounds like I may be out of date on the video games thing. Now the rumor mill sounds like the next xbox at least will use blu ray. (which will make sony happy.) Apparently MS and Sony kicked the idea around and decided the blowback would be too intense.
