My god, someone in this day and age are complaining about using the fucking disk(s) on a console?
*Plays Final Fantasy 7, reaches end of disk one, gets a prompt telling me to insert disk two, takes 5-10 seconds to insert the second disk, continues playing the game* Oh the horror
*Plays The Witcher 2 on Xbox, gets a prompt to insert disk two, takes 5-10 seconds to insert the second disk, continues playing the game* Oh the horror
Rinse and repeat for Final Fantasy XIII, L.A Noire, and other games on other systems that used multiple disks.
Personally, my objection to using a disk when it isn't an actual requirement (i.e. the machine has some other storage the game could be moved to) goes more along the lines of "I can't make a backup (either technically or legally), they won't replace the disc at cost
and me handling the disc degrades the quality and every time it is in the machine, I'm risking it being scratching, grinded into dust or exploding
 And yes, this one has happened to me personally.
It is not the inconvenience of changing disks, it is more the unnecessary risk of damage my property is being exposed to.
