I'm actually annoyed with these changes; they have reverted back to the Xbox 360 way of doings things;
* Disk must be in the drive to play
* Share games by lending the disk.
The previous scheme, while it would not be befinical to some due to the 24 hour requirement, did allow for some exciting new ideas (which we've got used to with Steam);
* Access my games anywhere without needing a disk
* Share the game with my family who live away from me
