"The optical drive, which supports 100GB optical discs "
Oh man, Just think of how great lossless audio would sound if those 700MB CDs were replaced with... well anything mordern, really.
Probably not Blu-Ray since PC support and DRM for that was so bad it basically killed optical media (not to forget how slow those live ad-filled menus are)... and nothing flash-based since it would be crapped up with DRM, but maybe like a single layer DVD or something, at least... which they would also crap up with DRM... Actually maybe they shouldn't touch CDs since it was the last good physical music format.
