i wonder what they were thinking when they devised that experiment.
"we just got a call saying that the xbox scratched disks when you move it"
"what are we gonna do?"
"lets try it just to make sure"
"ok, *moves xbox* *grinding noise* yup that scratched the disk"
"lets do it again just to make sure"
i mean, why would you need to keep moving the console while it was on anyway. and then proclaim it to be the fault of the manufacture when it scratches a disk. when those disks are spinning there's a huge amount of force on them. you can feel this force when you hold a fan in your hand while its on, and thats nothing compared to a DVD.
i bet there's a notice in the manual that says do not move the console while it is turned on or something similar.
